Do Buddhas have precognition? Do they know what events are going to happen before they do?
Obviously, the Buddha knows that he will not be reborn, and he knows what will generate a good rebirth, and what a bad. Are any of these destinies both assured and knowable?
According to Early Buddhism and the Bhagavadgita, By Kashi Nath Upadhyaya, p84, the Buddha "seems" to have claimed that he does not have "unlimited" knowledge of the future.
But I wondered if Buddhas had any certain knowledge of the future, aside from their not being reborn. Or perhaps, though the future is not fully predetermined (ibid), they can have certain knowledge of events aside from not being reborn.
Think not of the past but of the future. Constantly maintain the future thoughts to be good. This is what we call the Sambhogakāya.
Just one single evil thought could destroy the good karma that has continued for one thousand years; and just one single good thought in turn could destroy the evil karma that has lived for one thousand years. If the future thoughts are always good, you may call this the Sambhogakāya. The discriminative thinking arising from the Dharmakāya (法身↔fashen "Truth body") is called the Nirmanakāya (化身↔huashen "transformation body"). The successive thoughts that forever involve good are thus the Sambhogakāya.
if they don't, and the Buddha-nature is identical to the body, then maye it could be said (likely not) that rebirth has no phenomena whatsoever?
