Manduka Upanishad:~ Brahman must be realized in the waking state when all objects are present to consciousness, otherwise, it is nonsense. Page 65: v.10.

Manduka Upanishad:~"Sleep does not exist in Turiya”: This emphatically disproves the mystic use of sleep as an analogy for Brahman. Page 69.

Manduka Upanishad:~This means that objects do not disappear, they are there, and yet they are non-dual. Disillusionment is not the same as appearance. Page 74. v. 17

If you say deep sleep state as Brahman then everybody will take a sleeping pill or hemp, no one will bother about Self-realization.

Deep sleep is still a state of ignorance because we become aware of the deep sleep experience in the waking experience. the waking experience is a state of ignorance.

Deep sleep is an analogy to realize the three states changing. The one that witnesses the changes is the changeless Soul. Grasping the existence of the changeless witness of the three states leads to Self-awareness.

The nature of the Soul is like deep sleep. We must have the same repose of the deep sleep in the waking experience by realizing that all three states are created out of consciousness.

Sage Sankara: ~VC~ if the universe be true, let it then be perceived in the state of deep sleep also. As it is not at all perceived, it must be unreal and false like dreams.

Remember:~

The mind is virtually the universe. The universe appears as waking or dream (duality) and disappears deep sleep (nonduality). Efforts should be made to understand the mind.

Advaitic is wisdom is ancient truth preserved as a secret by sages of truth.

Every minute the waking experience is changing. The waking experience becomes deep sleep and deep sleep becomes the dream. Thus, their continuous change is going on and on in consciousness.

The one that appears as waking, the one that appears as a dream, and one that becomes the deep sleep is the Soul, which is present in the form of consciousness.

Thus, all three states are created out of single stuff and that stuff is consciousness.

Thus, one which becomes duality (waking or dream) and the one which becomes non-duality (deep sleep) is the same consciousness.

Thus, consciousness alone is real and all the three states are merely an illusion.

Remember:~

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

In deep sleep the Soul is awake, ignorance vanishes, and the Soul, the 'Self' remains in its own awareness.

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