But it does not end here. There is a still higher plane upon which the mind can work. It can go beyond consciousness. Just as unconscious work is beneath consciousness, so there is another work which is above consciousness, and which also is not accompanied with the feeling of egoism. The feeling of egoism is only on the middle plane. When the mind is above or below that line, there is no feeling of "I", and yet the mind works. When the mind goes beyond this line of self-consciousness, it is called Samâdhi or superconsciousness. How, for instance, do we know that a man in Samadhi has not gone below consciousness, has not degenerated instead of going higher? In both cases the works are unaccompanied with egoism. The answer is, by the effects, by the results of the work, we know that which is below, and that which is above. When a man goes into deep sleep, he enters a plane beneath consciousness. He works the body all the time, he breathes, he moves the body, perhaps, in his sleep, without any accompanying feeling of ego; he is unconscious, and when he returns from his sleep, he is the same man who went into it. The sum total of the knowledge which he had before he went into the sleep remains the same; it does not increase at all. No enlightenment comes. But when a man goes into Samadhi, if he goes into it a fool, he comes out a sage.
