It is erroneous to believe the general impression is that the universe disappears to a Gnani, that he sees nothing in Samadhi. Only deluded persons will have such an impression?

Nothing is destroyed. Only ignorance disappears and the unreal nature of the universe is exposed. The universe which appears as the waking experience is a dualistic illusion.

A Gnani has the full and firm conviction that the world in which he exists is nothing but the consciousness in the midst of dualistic illusion.

The Soul, the Self, being aware of its true nature in the midst of dualistic illusion is called Self-awareness.

The universe or the waking experience will not disappear. It is there always, but the unreal nature of the waking experience is exposed in the midst of dualistic illusion through Advaitic wisdom.

If one thinks its mere disappearance in the Yogic Samadhi is the ultimate Truth or Brahman, then he would get it in deep sleep. Thus, the yogic Samadhi is not the Advaitic wisdom. : ~ Santthosh Kumaar
