The universe appears as a waking or dream (duality) and disappears as the Soul in deep sleep (nonduality).+

Ignorance is the cause of the dualistic illusion. The dualistic illusion appears as ‘I’. The ‘I’ is present in the form of the mind. 

The mind is present in the form of the universe. The universe appears as a waking or dream (duality) and disappears as the Soul in deep sleep (nonduality)

Ignorance of the ‘Self’ hidden by the dualistic illusion prevents one from realizing the ‘Self’.

The individual experience of birth, life, death, and the world is a reality within the waking experience but the waking experience itself is a dualistic illusion.

The individual experience of birth, life, death, and the world is nothing to do with the Soul, the Self. From the Standpoint of the Soul, the Self, The individual experience of birth, life, death, and the world is merely an illusion.

When the whole experience of birth, life, death, and the world is negated then what is left is the Soul, the Self.

When the Soul wakes up from its sleep of ignorance and remains in its own awareness then the reality of the individual experience of birth, life, death, and the world becomes unreal. In the same way, the dream becomes unreal when the waking takes place.

Find out to realize: ~

What is it that becomes waking

What is it that becomes the dream

What is it that remains without waking and dream in deep sleep?

Remember:~

It is the Soul, the Self that becomes the waking (duality)

It is the Soul, that becomes the dream (duality)

It is the Soul, which is present in the form of consciousness that remains without waking or dream, in deep sleep(nonduality).: ~ Santthosh Kumaar
