The Buddha was asked: "Is there only one summit of consciousness or are there several?"Digha Nikaya
He replied: "One and several. As one state of consciousness is realized, then the next is seen. Thus there are several and there is one."
He was then asked: "Which is first, awareness or knowledge?"
"Awareness arises first and then comes knowledge. One can then say, 'Because of my awareness, I know this as a fact.'"
