Enlightenment is the "full comprehension of a situation".[web 1] The term is commonly used to denote the Age of Enlightenment,[note 1] but is also used in Western cultures in a religious context. It translates several Buddhist terms and concepts, most notably bodhi,[note 2] kensho and satori. Related terms from Asian religions are moksha (liberation) in Hinduism, Kevala Jnana in Jainism, and ushta in Zoroastrianism.
In Christianity, the word "enlightenment" is rarely used, except to refer to the Age of Enlightenment and its influence on Christianity. Roughly equivalent terms in Christianity may be illumination, kenosis, metanoia, revelation, salvation, theosis, and conversion.
Asian cultures and religions
The English term enlightenment is the western translation of the abstract noun bodhi, the knowledge or wisdom, or awakened intellect, of a Buddha.[web 2] The verbal root budh- means "to awaken," and its literal meaning is closer to "awakening." Although its most common usage is in the context of Buddhism, the term buddhi is also used in other Indian philosophies and traditions. The term "enlightenment" was popularised in the Western world through the 19th century translations of Max Müller. It has the western connotation of a sudden insight into a transcendental truth or reality.
The term is also being used to translate several other Buddhist terms and concepts, which are used to denote insight (prajna, kensho and satori); knowledge (vidhya); the "blowing out" (Nirvana) of disturbing emotions and desires and the subsequent freedom or release (vimutti); and the attainment of Buddhahood, as exemplified by Gautama Buddha.
What exactly constituted the Buddha's awakening is unknown. It may probably have involved the knowledge that liberation was attained by the combination of mindfulness and dhyāna, applied to the understanding of the arising and ceasing of craving. The relation between dhyana and insight is a core problem in the study of Buddhism, and is one of the fundamentals of Buddhist practice.
Deep down in people’s minds, there is an underlying dissatisfaction with the way things are. People want many things to be different from the way they actually are. There is a craving for becoming something that one is not and there is a resistance to the way things are. Everyone is moving towards a goal, a destination that is in the future. The hopes of arriving at that destination seem to give some solace and if those hopes and dreams are threatened, we tend to suffer. This burning uneasiness and dissatisfaction can be likened to a fire that is burning. The extinction of this fire is enlightenment. The word ‘Nirvana’ means extinction.
In the western world the concept of spiritual enlightenment has become synonymous with self-realization and the true self and false self, being regarded as a substantial essence being covered over by social conditioning.[page needed], [page needed], [page needed], [page needed]
In Indian religions moksha (Sanskrit: मोक्ष mokṣa; liberation) or mukti (Sanskrit: मुक्ति; release —both from the root muc "to let loose, let go") is the final extrication of the soul or consciousness (purusha) from samsara and the bringing to an end of all the suffering involved in being subject to the cycle of repeated death and rebirth (reincarnation).
Advaita Vedanta (IAST Advaita Vedānta; Sanskrit: अद्वैत वेदान्त [ɐdʋaitɐ ʋeːdaːntɐ]) is a philosophical concept where followers seek liberation/release by recognizing identity of the Self (Atman) and the Whole (Brahman) through long preparation and training, usually under the guidance of a guru, that involves efforts such as knowledge of scriptures, renunciation of worldly activities, and inducement of direct identity experiences. Originating in India before 788 AD, Advaita Vedanta is widely considered the most influential and most dominant[web 3] sub-school of the Vedānta (literally, end or the goal of the Vedas, Sanskrit) school of Hindu philosophy. Other major sub-schools of Vedānta are Viśishṭādvaita and Dvaita; while the minor ones include Suddhadvaita, Dvaitadvaita and Achintya Bhedabheda.
Advaita (literally, non-duality) is a system of thought where "Advaita" refers to the identity of the Self (Atman) and the Whole (Brahman).[note 3] Recognition of this identity leads to liberation. Attaining this liberation supposedly takes a long preparation and training under the guidance of a guru, however Ramana Maharshi called his death experience akrama mukti, "sudden liberation", as opposed to the krama mukti, "gradual liberation" as in the Vedanta path of Jnana yoga.
The key source texts for all schools of Vedānta are the Prasthanatrayi—the canonical texts consisting of the Upanishads, the Bhagavad Gita and the Brahma Sutras. The first person to explicitly consolidate the principles of Advaita Vedanta was Shankara Bhagavadpada, while the first historical proponent was Gaudapada, the guru of Shankara's guru Govinda Bhagavatpada.
Shankara systematized the works of preceding philosophers. His system of Vedanta introduced the method of scholarly exegesis on the accepted metaphysics of the Upanishads. This style was adopted by all the later Vedanta schools.
In half a couplet I state, what has been stated by crores of texts;
that is Brahman alone is real, the world is mithyā (not independently existent),
In the 19th century, Vivekananda played a major role in the revival of Hinduism, and the spread of Advaita Vedanta to the West via the Ramakrishna Mission. His interpretation of Advaita Vedanta has been called "Neo-Vedanta".
In a talk on "The absolute and manifestation" given in at London in 1896 Swami Vivekananda said,
I may make bold to say that the only religion which agrees with, and even goes a little further than modern researchers, both on physical and moral lines is the Advaita, and that is why it appeals to modern scientists so much. They find that the old dualistic theories are not enough for them, do not satisfy their necessities. A man must have not only faith, but intellectual faith too".[web 4]
Vivekananda emphasized samadhi as a means to attain liberation. Yet this emphasis is not to be found in the Upanishads nor in Shankara. For Shankara, meditation and Nirvikalpa Samadhi are means to gain knowledge of the already existing unity of Brahman and Atman, not the highest goal itself:
[Y]oga is a meditative exercise of withdrawal from the particular and identification with the universal, leading to contemplation of oneself as the most universal, namely, Consciousness. This approach is different from the classical yoga of complete thought suppression.
Without calling into question the right of any philosopher to interpret Advaita according to his own understanding of it, [...] the process of Westernization has obscured the core of this school of thought. The basic correlation of renunciation and Bliss has been lost sight of in the attempts to underscore the cognitive structure and the realistic structure which according to Samkaracarya should both belong to, and indeed constitute the realm of māyā.
Neo-Advaita is a new religious movement based on a modern, Western interpretation of Advaita Vedanta, especially the teachings of Ramana Maharshi. Neo-Advaita is being criticized[note 6][note 7][note 8] for discarding the traditional prerequisites of knowledge of the scriptures and "renunciation as necessary preparation for the path of jnana-yoga". Notable neo-advaita teachers are H. W. L. Poonja, his students Gangaji Andrew Cohen,[note 9], Madhukar and Eckhart Tolle.
The prime means to reach moksha is through the practice of yoga (Sanskrit, Pāli: योग, /ˈjəʊɡə/, yoga) which is a commonly known generic term for physical, mental, and spiritual disciplines which originated in ancient India. Specifically, yoga is one of the six āstika ("orthodox") schools of Hindu philosophy. Various traditions of yoga are found in Hinduism, Buddhism, Jainism and Sikhism.[note 10]
Pre–philosophical speculations and diverse ascetic practices of first millennium BCE were systematized into a formal philosophy in early centuries CE by the Yoga Sutras of Patanjali. By the turn of the first millennium, Hatha yoga emerged as a prominent tradition of yoga distinct from the Patanjali's Yoga Sutras. While the Yoga Sutras focus on discipline of the mind, Hatha yoga concentrates on health and purity of the body.
Hindu monks, beginning with Swami Vivekananda, brought yoga to the West in the late 19th century. In the 1980s, yoga became popular as a physical system of health exercises across the Western world. Many studies have tried to determine the effectiveness of yoga as a complementary intervention for cancer, schizophrenia, asthma and heart patients. In a national survey, long-term yoga practitioners in the United States reported musculo–skeletal and mental health improvements.
- Samanyasa or Sampattis, the "fourfold discipline" (sādhana-catustaya), cultivating the following four qualities:[web 11]
- Nityānitya vastu viveka (नित्यानित्य वस्तु विवेकम्) – The ability to correctly discriminate (viveka) between the eternal (nitya) substance (Brahman) and the substance that is transitory existence (anitya).
- Ihāmutrārtha phala bhoga virāga (इहाऽमुत्रार्थ फल भोगविरागम्) – The renunciation (virāga) of enjoyments of objects (artha phala bhoga) in this world (iha) and the other worlds (amutra) like heaven etc.
- Śamādi ṣatka sampatti (शमादि षट्क सम्पत्ति) – the sixfold qualities,
- Śama (control of the antahkaraṇa).[web 12]
- Dama (the control of external sense organs).
- Uparati (the cessation of these external organs so restrained, from the pursuit of objects other than that, or it may mean the abandonment of the prescribed works according to scriptural injunctions).[note 11]
- Titikṣa (the tolerating of tāpatraya).
- Śraddha (the faith in Guru and Vedas).
- Samādhāna (the concentrating of the mind on God and Guru).
- Mumukṣutva (मुमुक्षुत्वम्) – The firm conviction that the nature of the world is misery and the intense longing for moksha (release from the cycle of births and deaths).
- Sravana, listening to the teachings of the sages on the Upanishads and Advaita Vedanta, and studying the Vedantic texts, such as the Brahma Sutras. In this stage the student learns about the reality of Brahman and the identity of atman;
- Manana, the stage of reflection on the teachings;
- Dhyana, the stage of meditation on the truth "that art Thou".
The paths of bhakti yoga and karma yoga are subsidiary.
In bhakti yoga, practice centers on the worship God in any way and in any form, like Krishna or Ayyappa. Adi Shankara himself was a proponent of devotional worship or Bhakti. But Adi Shankara taught that while Vedic sacrifices, puja and devotional worship can lead one in the direction of jnana (true knowledge), they cannot lead one directly to moksha. At best, they can serve as means to obtain moksha via shukla gati.
Karma yoga is the way of doing our duties, in disregard of personal gains or losses. According to Sri Swami Sivananda,
Karma Yoga is consecration of all actions and their fruits unto the Lord. Karma Yoga is performance of actions dwelling in union with the Divine, removing attachment and remaining balanced ever in success and failure. Karma Yoga is selfless service unto humanity. Karma Yoga is the Yoga of action which purifies the heart and prepares the Antahkarana (the heart and the mind) for the reception of Divine Light or attainment of Knowledge of the Self. The important point is that you will have to serve humanity without any attachment or egoism.[web 13]
Jainism (//; Sanskrit: जैनधर्म Jainadharma, Tamil: சமணம் Samaṇam, Bengali: জৈনধর্ম Jainadharma, Telugu: జైనమతం Jainamataṁ, Malayalam: ജൈനമതം Jainmat, Kannada: ಜೈನ ಧರ್ಮ Jaina dharma), is an Indian religion that prescribes a path of non-violence towards all living beings. Its philosophy and practice emphasize the necessity of self-effort to move the soul toward divine consciousness and liberation. Any soul that has conquered its own inner enemies and achieved the state of supreme being is called a jina ("conqueror" or "victor"). The ultimate status of these perfect souls is called siddha. Ancient texts also refer to Jainism as shramana dharma (self-reliant) or the "path of the nirganthas" (those without attachments or aversions).
In Jainism highest form of pure knowledge a soul can attain is called Kevala Jnana (Sanskrit: केवलज्ञान) or Kevala Ṇāṇa (Prakrit: केवल णाण). which means "absolute or perfect" and Jñāna, which means "knowledge". Kevala is the state of isolation of the jīva from the ajīva attained through ascetic practices which burn off one's karmic residues, releasing one from bondage to the cycle of death and rebirth. Kevala Jñāna thus means infinite knowledge of self and non-self, attained by a soul after annihilation of the all ghātiyā karmas. The soul which has reached this stage achieves moksa or liberation at the end of its life span.
Mahavira, 24th thirthankara of Jainism, is said to have practised rigorous austerities for 12 years before he attained enlightenment,
During the thirteenth year, in the second month of summer, in the fourth fortnight, the light (fortnight) of Vaisakha, on its tenth day, when the shadow had turned towards the east and the first wake was over, on the day called Suvrata, in the Muhurta called Vigaya, outside of the town Grimbhikagrama on the bank of the river Rjupalika, not far from an old temple, in the field of the householder Samaga, under a Sal tree, when the moon was in conjunction with the asterism Uttara Phalguni, (the Venerable One) in a squatting position with joined heels, exposing himself to the heat of the sun, after fasting two and a half days without drinking water, being engaged in deep meditation, reached the highest knowledge and intuition, called Kevala, which is infinite, supreme, unobstructed, unimpeded, complete, and full.
Kevala Jñāna is one of the five major events in the life of a Tirthankara and is known as Keval Jñāna Kalyanaka and celebrated of all gods. Lord Mahavira's Kaivalya was said to have been celebrated by the demi-gods, who constructed the Samosarana or a grand preaching assembly for him.
In the Western world the concept of enlightenment in a religious context acquired a romantic meaning. It has become synonymous with self-realization and the true self, which is being regarded as a substantial essence which is covered over by social conditioning.[note 12]
The use of the Western word enlightenment is based on the supposed resemblance of bodhi with Aufklärung, the independent use of reason to gain insight into the true nature of our world. As a matter of fact there are more resemblances with Romanticism than with the Enlightenment: the emphasis on feeling, on intuitive insight, on a true essence beyond the world of appearances.
Awakening: Historical period of renewed interest in religion
The equivalent term "awakening" has also been used in a Christian context, namely the Great Awakenings, several periods of religious revival in American religious history. Historians and theologians identify three or four waves of increased religious enthusiasm occurring between the early 18th century and the late 19th century. Each of these "Great Awakenings" was characterized by widespread revivals led by evangelical Protestant ministers, a sharp increase of interest in religion, a profound sense of conviction and redemption on the part of those affected, an increase in evangelical church membership, and the formation of new religious movements and denominations.
Another equivalent term is Illuminationism, which was also used by Paul Demieville in his work The Mirror of the Mind, in which he made a distinction between "illumination subie" and "illumination graduelle".[web 14] Illuminationism is a doctrine according to which the process of human thought needs to be aided by divine grace. It is the oldest and most influential alternative to naturalism in the theory of mind and epistemology.[web 15] It was an important feature of ancient Greek philosophy, Neoplatonism, medieval philosophy, and in particular, the Illuminationist school of Islamic philosophy.
Augustine was an important proponent of Illuminationism, stating that everything we know is taught to us by God as He casts His light over the world,[web 16] saying that "The mind needs to be enlightened by light from outside itself, so that it can participate in truth, because it is not itself the nature of truth. You will light my lamp, Lord,"  and "You hear nothing true from me which you have not first told me." Augustine's version of illuminationism is not that God gives us certain information, but rather gives us insight into the truth of the information we received for ourselves.
Romanticism and transcendentalism
This romantic idea of enlightenment as insight into a timeless, transcendent reality has been popularized especially by D.T. Suzuki.[web 17][web 18] Further popularization was due to the writings of Heinrich Dumoulin.[web 19] Dumoulin viewed metaphysics as the expression of a transcendent truth, which according to him was expressed by Mahayana Buddhism, but not by the pragmatic analysis of the oldest Buddhism, which emphasizes anatta. This romantic vision is also recognizable in the works of Ken Wilber.
...most of them labour under the old cliché that the goal of Buddhist psychological analysis is to reveal the hidden mysteries in the human mind and thereby facilitate the development of a transcendental state of consciousness beyond the reach of linguistic expression.
A common reference in Western culture is the notion of "enlightenment experience". This notion can be traced back to William James, who used the term "religious experience" in his book, The Varieties of Religious Experience. Wayne Proudfoot traces the roots of the notion of "religious experience" further back to the German theologian Friedrich Schleiermacher (1768–1834), who argued that religion is based on a feeling of the infinite. The notion of "religious experience" was used by Schleiermacher to defend religion against the growing scientific and secular critique.
It was popularised by the Transcendentalists, and exported to Asia via missionaries. Transcendentalism developed as a reaction against 18th-century rationalism, John Locke's philosophy of Sensualism, and the predestinationism of New England Calvinism. It is fundamentally a variety of diverse sources such as Hindu texts like the Vedas, the Upanishads and the Bhagavad Gita, various religions, and German idealism.
The notion of "experience" has been criticised. Robert Sharf points out that "experience" is a typical Western term, which has found its way into Asian religiosity via western influences.[note 14] The notion of "experience" introduces a false notion of duality between "experiencer" and "experienced", whereas the essence of kensho is the realisation of the "non-duality" of observer and observed. "Pure experience" does not exist; all experience is mediated by intellectual and cognitive activity. The specific teachings and practices of a specific tradition may even determine what "experience" someone has, which means that this "experience" is not the proof of the teaching, but a result of the teaching. A pure consciousness without concepts, reached by "cleansing the doors of perception",[note 15] would be an overwhelming chaos of sensory input without coherence.
The word "enlightenment" is not generally used in Christian contexts for religious understanding or insight. More commonly used terms in the Christian tradition are religious conversion and revelation.
Lewis Sperry Chafer (1871–1952), one of the founders of Dispensationalism, uses the word "illuminism". Christians who are "illuminated" are of two groups, those who have experienced true illuminism (biblical) and those who experienced false illuminism (not from the Holy Spirit).
Christian interest in eastern spirituality has grown throughout the 20th century. Notable Christians, such as Hugo Enomiya-Lassalle and AMA Samy, have participated in Buddhist training and even become Buddhist teachers themselves. In a few places Eastern contemplative techniques have been integrated in Christian practices, such as centering prayer.[web 23] But this integration has also raised questions about the borders between these traditions.[web 24]
Western esotericism and mysticism
Western and Mediterranean culture has a rich tradition of esotericism and mysticism. The Perennial philosophy, basic to the New Age understanding of the world, regards those traditions as akin to Eastern religions which aim at awakening/ enlightenment and developing wisdom. The hypothesis that all mystical traditions share a "common core", is central to New Age, but contested by a diversity of scientists like Katz and Proudfoot.
A popular western understanding sees "enlightenment" as "nondual consciousness", "a primordial, natural awareness without subject or object".[web 25] It is used interchangeably with Neo-Advaita.
This nondual consciousness is seen as a common stratum to different religions. Several definitions or meanings are combined in this approach, which makes it possible to recognize various traditions as having the same essence. According to Renard, many forms of religion are based on an experiential or intuitive understanding of "the Real"
This idea of nonduality as "the central essence" is part of a modern mutual exchange and synthesis of ideas between western spiritual and esoteric traditions and Asian religious revival and reform movements.[note 16] Western predecessors are, among others, New Age, Wilber's synthesis of western psychology and Asian spirituality, the idea of a Perennial Philosophy, and Theosophy. Eastern influences are the Hindu reform movements such as Aurobindo's Integral Yoga and Vivekananda's Neo-Vedanta, the Vipassana movement, and Buddhist modernism. A truly syncretistic influence is Osho and the Rajneesh movement, a hybrid of eastern and western ideas and teachings, and a mainly western group of followers.
Religious experience as cognitive construct
These experiences are cognitive in that, allegedly at least, the subject of the experience receives a reliable and accurate view of what, religiously considered, are the most important features of things. This, so far as their religious tradition is concerned, is what is most important about them. This is what makes them "salvific" or powerful to save.
Yet, just like the very notion of "religious experience" is shaped by a specific discourse and habitus, the "uniformity of interpretation" may be due to the influence of religious traditions which shape the interpretation of such experiences.
Various religious experiences
Yandell discerns various "religious experiences" and their corresponding doctrinal settings, which differ in structure and phenomenological content, and in the "evidential value" they present. Yandell discerns five sorts:
- Numinous experiences – Monotheism (Jewish, Christian, Vedantic, Sufi Islam)
- Nirvanic experiences – Buddhism, "according to which one sees that the self is but a bundle of fleeting states"
- Kevala experiences – Jainism, "according to which one sees the self as an indestructible subject of experience"
- Moksha experiences – Hinduism, Brahman "either as a cosmic person, or, quite differently, as qualityless"
- Nature mystical experience
Various philosophers and cognitive scientists state that there is no "true self" or a "little person" (homunculus) in the brain that "watches the show," and that consciousness is an emergent property that arise from the various modules of the brain in ways that are yet far from understood. According to Susan Greenfield, the "self" may be seen as a composite, whereas Douglas R. Hofstadter describes the sense of "I" as a result of cognitive process.
This is in line with the Buddhist teachings, which state that
[...] what we call 'I' or 'being,' is only a combination of physical and mental aggregates which are working together interdependently in a flux of momentary change within the law of cause and effect, and that there is nothing, permanent, everlasting, unchanging, and eternal in the whole of existence.
Several users of entheogens throughout the ages have claimed experiences of spiritual enlightenment with the use of these substances, their use and prevalence through history is well recorded, and continues today. In modern times we have seen increased interest in these practices, for example the rise of interest in Ayahuasca. The psychological effects of these substances have been subject to scientific research focused on understanding their physiological basis. While entheogens do produce glimpses of higher spiritual states, these are always temporary, fading with the effects of the substance. Permanent enlightenment requires making permanent changes in your consciousness.
- "Mankind's final coming of age, the emancipation of the human consciousness from an immature state of ignorance and error."
- When referring to the Enlightenment of the Buddha (samma-sambodhi) and thus to the goal of the Buddhist path, the word enlightenment is normally translating the Pali and Sanskrit word bodhi
- "Brahman" is not to be confused with Brahma, the Creator and one third of the Trimurti along with Shiva, the Destroyer and Vishnu, the Preserver.
- The authorship of this work is disputed. Most 20th-century academic scholars feel it was not authored by Sankara, and Swami Sacchidanandendra Saraswathi of Holenarsipur concurs.

- Marek: "Wobei der Begriff Neo-Advaita darauf hinweist, dass sich die traditionelle Advaita von dieser Strömung zunehmend distanziert, da sie die Bedeutung der übenden Vorbereitung nach wie vor als unumgänglich ansieht. (The term Neo-Advaita indicating that the traditional Advaita increasingly distances itself from this movement, as they regard preparational practicing still as inevitable)
- Alan Jacobs: Many firm devotees of Sri Ramana Maharshi now rightly term this western phenomenon as 'Neo-Advaita'. The term is carefully selected because 'neo' means 'a new or revived form'. And this new form is not the Classical Advaita which we understand to have been taught by both of the Great Self Realised Sages, Adi Shankara and Ramana Maharshi. It can even be termed 'pseudo' because, by presenting the teaching in a highly attenuated form, it might be described as purporting to be Advaita, but not in effect actually being so, in the fullest sense of the word. In this watering down of the essential truths in a palatable style made acceptable and attractive to the contemporary western mind, their teaching is misleading.
- See for other examples Conway [web 5] and Swartz [web 6]
- Presently Cohen has distanced himself from Poonja, and calls his teachings "Evolutionary Enlightenment". What Is Enlightenment, the magazine published by Cohen's organisation, has been critical of neo-Advaita several times, as early as 2001. See.[web 7][web 8][web 9]

- Jean-Jacques Rousseau was an important influence on the development of this idea. See for example Osho's teachings for a popularisation of this idea.
- James also gives descriptions of conversion experiences. The Christian model of dramatic conversions, based on the role-model of Paul's conversion, may also have served as a model for Western interpretations and expectations regarding "enlightenment", similar to Protestant influences on Theravada Buddhism, as described by Carrithers: "It rests upon the notion of the primacy of religious experiences, preferably spectacular ones, as the origin and legitimation of religious action. But this presupposition has a natural home, not in Buddhism, but in Christian and especially Protestant Christian movements which prescribe a radical conversion." See Sekida for an example of this influence of William James and Christian conversion stories, mentioning Luther and St. Paul. See also McMahan for the influence of Christian thought on Buddhism.
- Robert Sharf: "[T]he role of experience in the history of Buddhism has been greatly exaggerated in contemporary scholarship. Both historical and ethnographic evidence suggests that the privileging of experience may well be traced to certain twentieth-century reform movements, notably those that urge a return to zazen or vipassana meditation, and these reforms were profoundly influenced by religious developments in the west [...] While some adepts may indeed experience "altered states" in the course of their training, critical analysis shows that such states do not constitute the reference point for the elaborate Buddhist discourse pertaining to the "path".
- William Blake: "If the doors of perception were cleansed every thing would appear to man as it is, infinite. For man has closed himself up, till he sees all things thru' narrow chinks of his cavern."[web 22]
