In order to do so one would have to suffer the loss of self. So yes it is yet what is its worth if you have no sense of self. Everything a person does thier entire life is in order to satiate the desires drawn from our self. In order to evolve into a higher order of consciousness one would have to devalue the ideal of ones self. Abolish the entire line of thought in fact.

There are those who have claimed to do this; Bhuddha, Jesus, Mohammed; etc etc. The greatest way to prove one has lost all sense of self is to sacrifice ones self.
