If you mean that literally [that nagarjuna does not mean to say anything about existence and non existence] then i do not understand. the commentaries on nagarjuna mention existence so many times!retrofuturist wrote:As sunyata pertains to the Dharma, it accordingly pertains to the phenomenological, and not to concerns of existence and non-existence. As I understand it, this is the thrust of Nagarjuna's work on sunyata.
going back to the OP... it is true is it not that in theravada the doctrine of selflessness is just a conventional truth or "raft" that does not describe the goal [because nothing does] and which is to be abandoned when there. assuming that buddhas know reality, doesn't that mean that reality is not without a self?
