Only The "I" Exists in Deep Sleep

"Consciousness never parts with you in any of the three states. In deep sleep you are conscious of deep rest or peace. Inference is possible only of those things which have not been experienced. The fact that you had a deep sleep or profound rest is your direct experience and you only remember it when you come to the waking state. It can never be an inference. Experience alone can be remembered. The fact that you were present throughout the deep sleep can also never be denied. The only three factors thus found present in deep sleep are Consciousness, peace and yourself. All these are objectless and can never be objectified.In other words, they are all subjective. But there can only be one subject and that is the 'I- Principle'. So none of these three can be the result of inference since they are all experience itself."
