In waking, the Soul sleeps in ignorance therefore the universe (I) rises.+

In waking, the Soul sleeps in ignorance, therefore, the universe (I) rises.  In deep sleep the Soul is awake, the ignorance vanishes, and the Soul, the 'Self' remains in its own awareness.

The ‘I’ becomes ‘I’-less in deep sleep and the ‘I’-less appear as waking or dream (duality).   In ignorance, the Soul appears as the ‘I’ and the Soul disappear ‘I-less when the ignorance vanishes.

The ‘I’ (mind) and ‘I-less (Soul) both are one in essence. From the standpoint of the Soul, the  Self, the three states are merely an illusion. The ‘I’ never exists in reality.

"The ‘I’ is impermanent. The ‘I’ comes and goes as waking or dream, and disappears as deep sleep. There must be something permanent, to register the coming and going, of the ‘I’. 

The ‘I’ itself is an illusion. The Soul is the witness of the ‘I’ is permanent and eternal.

The Soul is the Self. The Soul is present in the form of consciousness. Consciousness pervades in everything and everywhere in all three states. 

Thus, the Self-knowledge or Brahma Gnana or Atma Gnana has to be acquired to unfold the mystery of the ‘I’, which is the dualistic illusion. :~Santthosh Kumaaar
