Awakening or Enlightenment. Bodhi in Buddhism is the understanding possessed by a Buddha regarding the true nature of things. It is traditionally translated into English with the word enlightenment, though its literal meaning is closer to "awakened." The verbal root "budh" means to awaken.
Bodhi is presented in the Nikayas as knowledge of the causal mechanism by which beings incarnate into material form and experience suffering. Although its most common usage is in the context of Buddhism, the term buddhi is also used in other Indian philosophies and traditions.
