Bodhi, from a root meaning to wake, is the awakening the Buddha attained under the tree that took its name, the bodhi tree, at Bodh Gayā. It is the direct knowledge of the four noble truths and the end of ignorance. The Mahāyāna distinguishes the awakening of disciples, solitary buddhas and buddhas.
