Buddha

means the Awakened One, awakened from conventional delusion, primarily of a separated self, which develops into divisiveness (hatred, anger, etc.) and desire (craving, greed. etc.). These triplets are called the Triple Poisons, which poison and destroy body/mind/world system in ripple effect in space and time, resulting in samsara suffering. The Buddha was awakened from them and lived wakefully to avoid and freed from them through sitting and stilling karma (past/present/future action/habit/heredity).
