Our self (Soul) is maya (an illusion) where it is merely individual and finite, where it considers its separateness as absolute; it is satyam (truth) where it recognizes its essence in the universal and infinite, in the Supreme Self, in paramatman (God). This is what Christ means when he says, "Before Abraham was, I am" (i.e. before Abraham was God, who is the same that is in my soul - I am That.)
