The whole of this universe, therefore, is, as it were, a peculiar form; the Absolute is that ocean while you and I, and suns and stars, and everything else are various waves of that ocean. And what makes the waves different? Only the form, and that form is time, space, and causation, all entirely dependent on the wave. As soon as the wave goes, they vanish. As soon as the individual gives up this Maya, it vanishes for him and he becomes free. The whole struggle is to get rid of this clinging on to time, space, and causation, which are always obstacles in our way. What is the theory of evolution? What are the two factors? A tremendous potential power which is trying to express itself, and circumstances which are holding it down, the environments not allowing it to express itself. So, in order to fight with these environments, the power is taking new bodies again and again. An amoeba, in the struggle, gets another body and conquers some obstacles, then gets another body and so on, until it becomes man. Now, if you carry this idea to its logical conclusion, there must come a time when that power that was in the amoeba and which evolved as man will have conquered all the obstructions that nature can bring before it and will thus escape from all its environments.
