Shri Mataji: In the evolutionary process a human being has come out of a small little unicellular animal called Amoeba as they say in the science. But what is the purpose of this becoming a human being? The purpose of his becoming a human being is that he has to become the spirit. This vehicle of a human body, mind, is to express the spirit within you. Self realization is the epitome of our evolution. So we all have to become self realized. Without self we are in darkness. We are not aware of the all pervading power which is doing all the living work. All kinds of living work things we can not do. What we do is the dead work or the mental projections which recoil back upon ourselves. We must get to self realization that’s the goal of human ascent from amoeba to this stage.
