Theravada Buddhists base their view of the Buddha on the Pali Canon, which appear to be the oldest surviving Buddhist scriptures. From the accounts contained in the Pali Canon emerges the view that Buddha was a human being — a perfected human being. Buddha was also possessed of all the various supernatural powers, and mastered these to the greatest extent possible (Digha Nikaya 11: Kevatta Sutta). The body and mind of a Buddha (while alive) are impermanent and changing, just like the body and mind of ordinary people. A Buddha does recognize the unchanging nature of the Dharma, which is an eternal principle, and an unconditioned and timeless phenomenon.
