In Buddhism, the fig tree under which the Buddha sat when he attained enlightenment (bodhi) at Bodh Gaya (near Gaya, India). The tree growing on the site now is believed to be a descendant of the original, planted from a cutting of a tree in Sri Lanka that had been propagated from the original; both trees are sites of pilgrimage for Buddhists. The bo tree or a representation of its leaf has often been used as a symbol of the Buddha.

(Sanskrit and Pali: “awakening” or “enlightenment”) In Buddhism, the final enlightenment that ends the cycle of death and rebirth and leads to nirvana. This awakening transformed Siddhartha Gautama into the historical Buddha. Bodhi is achieved by ridding oneself of false beliefs and the hindrance of passions through the discipline of the Eightfold Path. Though not supported in canonical texts, commentaries give a threefold classification of bodhi: that of a perfectly enlightened one, or a Buddha; that of an independently enlightened one; and that of an arhat.

Although its most common usage by far is in the context of Buddhism, bodhi is also a technical term with various usages in other Indian philosophies and traditions.
Bodhi is an abstract noun formed from the verbal root budh (to awake, become aware, notice, know or understand,) corresponding to the verbs bujjhati (Pāli) and bodhati or budhyate (Sanskrit).
In early Buddhism, bodhi carried a meaning synonymous to nirvana, using only some different metaphors to describe the experience, which implied the extinction of raga (greed), dosa (hate) and moha (delusion). In the later school of Mahayana Buddhism, the status of nirvana was downgraded in some scriptures, coming to refer only to the extinction of greed and hate, implying that delusion was still present in one who attained nirvana, and that one needed to attain bodhi to eradicate delusion. Therefore, according to Mahayana Buddhism, the arahant has attained only nirvana, thus still being subject to delusion, while the bodhisattva not only achieves nirvana but full liberation from delusion as well. He thus attains bodhi and becomes a buddha. In Theravada Buddhism, bodhi and nirvana carry the same meaning, that of being freed from greed, hate and delusion. It should also be noted that in the Mahayana Mahaparinirvana Sutra, "Great Nirvana" (maha-nirvana) is equal in all respects to Bodhi and indeed is the state of perfect Buddhahood.
In Buddhism, bodhi means the awakening experience attained by Gautama Buddha and his accomplished disciples and refers to the unique consciousness of a fully liberated yogi. Bodhi is sometimes described as complete and perfect sanity, or awareness of the true nature of the universe. After attainment, it is believed that one is freed from the cycle of samsāra: birth, suffering, death and rebirth (see moksha). Bodhi is most commonly translated into English as enlightenment. This word conveys the insight and understanding (wisdom) possessed by a buddha and is similarly used in Christian mysticism to convey the saint's condition of being lit by a higher power - the merging of the human and the divine in theosis. There is no image of "light" contained in the term "bodhi", however. Rather, it expresses the notion of awakening from a dream and of being aware and knowing (reality). It is thus more accurate to think of bodhi as spiritual "awake-ness" or "awakenment", rather than "enlightenment" (although it is true that imagery of light is extraordinarily prevalent in many of the Buddhist scriptures).
Bodhi is attained when the ten fetters that bind a human being to the wheel of samsara have been dissolved; when the Four Noble Truths have been fully understood and all volitional conditioning has reached cessation (nirodha), giving rise to transcendent peace (nibbana). At this moment, the psychological roots of all greed (lobha), aversion (dosa), delusion (moha), ignorance (avijjā), craving (tanha) and ego-centered consciousness (attā) are completely uprooted.
Bodhi is the ultimate goal of Buddhist life (brahmacarya). It is achieved by observing the eightfold path, the development of the paramitas (virtues) and profound wisdom into the dependently arisen nature of phenomena.
Certain Mahayana Buddhist sutras stress that bodhi is always present and perfect, and simply needs to be "uncovered" or disclosed to purified vision. Thus the "Sutra of Perfect Awakening" has the Buddha teach that, like gold within its ore, bodhi is always there within the being's mind, but requires the obscuring mundane ore (the surrounding defilements of samsara and of impaired, unawakened perception) to be removed. The Buddha declares:
"Good sons, it is like smelting gold ore. The gold does not come into being because of smelting ... Even though it passes through endless time, the nature of the gold is never corrupted. It is wrong to say that it is not originally perfect. The Perfect Enlightenment of the Tathagata [Buddha] is also like this."
Similar doctrines are encountered in the Tathagatagarbha sutras, which tell of the immanent presence of the Buddha Principle (Buddha-dhatu/ Buddha-nature or Dharmakaya / Dhammakaya) within all beings. Here, the Tathagatagarbha (Buddha-Matrix) is tantamount to the indwelling transformative and liberational power of bodhi, which bestows an infinitude of unifying vision. The Buddha of the Shurangama Sutra states:
"My uncreated and unending profound Enlightenment accords with the Tathagatagarbha, which is absolute bodhi, and ensures my perfect insight into the Dharma realm [realm of Ultimate Truth], where the one is infinite and the infinite is one."
