All Buddhist schools have denied the existence of the self as an identical permanent substance. They have also universally rejected the notion of a supreme God. They have however accepted the reality of pre-existence and subsequent rebirth as well as the provisional efficiency of actions (Karma).
The Buddhist schools have replied to this objection with the doctrine of Interdependent Origination.
This work consists of the english language translations of some of Nagarjuna's most significant works such as Sunyatasaptati (Seventy Verses on Emptiness), Yuktisastika (Sixty Verses on Reasoning), Suhrllekha (Letter to a Good Friend) as well a short exposition on the doctrine of interdependent origination which forms the heart of Nagarjuna's (and according to him Buddha's) views about the nature of reality.
