Query: Which doctrine denies the concept of a permanent self or soul?
Context: Rebirth refers to a process whereby beings go through a succession of lifetimes as one of many possible forms of sentient life, each running from conception to death. The doctrine of anattā (Sanskrit anātman) rejects the concepts of a permanent self or an unchanging, eternal soul, as it is called in Hinduism and Christianity. According to Buddhism there ultimately is no such thing as a self independent from the rest of the universe.
