Deep sleep is not the same as non dual wisdom, for the latter exists when one sees the objective world and men; not when he is unaware of it.

Deep sleep is not the same as non dual wisdom, for the latter exists when one sees the objective world and men; not when he is unaware of it.

Three state analyses: one knows that there is a dream state or a deep sleep state only in the waking experience. Only by distinguishing it from waking one knows the meaning of sleep or dream apart from the waking experience. 

 Man who is sleeping or dreaming all the 24 hours, would know that there is a different state in existence, when he awakens. It is only by taking the whole of man's experience; waking cannot be separated from the other two states: one knows waking only by distinguishing it from dream.

The common people not know what is meant by sleep, waking and dream. Waking is that which comprehends through understanding the other two states. To shut out dream and sleep from inquiry is to prevent fullness of knowledge being got. It is wakeful state alone which gives the knowledge of the other states. It is impossible to arrive at truth when one reject so much data as sleep and dream, and confine himself  to waking alone.

 Seeker of truth has to take the waking experience which consists of the universe him to- gather. He has to ask the question to himself: What is the meaning of dream and sleep? Eventually he comes to a certain understanding about the truth of the entire existence, not merely a certain aspect of it.

Seeker of truth should not believe in the stories that in the next world after one dies he shall have his knowledge with him. Waking die every night but where, in deep sleep is all his knowledge, feeling-and personality? Suppose he never wake up from deep sleep. He never regains his separate self, or the world. It is the same in death. The world and him-self disappear then as in sleep.
