Only those who are perfectly satisfied with the Self, whose desires do not go beyond the Self, whose mind never strays out of the Self, to whom the Self is all in all, only those do not work. The rest must work. A current rushing down of its own nature falls into a hollow and makes a whirlpool, and, after running a little in that whirlpool, it emerges again in the form of the free current to go on unchecked. Each human life is like that current. It gets into the whirl, gets involved in this world of space, time, and causation, whirls round a little, crying out, "my father, my brother, my name, my fame", and so on, and at last emerges out of it and regains its original freedom. The whole universe is doing that. Whether we know it or not, whether we are conscious or unconscious of it, we are all working to get out of the dream of the world. Man's experience in the world is to enable him to get out of its whirlpool.
