Dear silence,
In Ajata Vada which has no difference for permanent turiya state, is what Gaudapada described in his Mandukya Karika.
There in that state, the world will NOT disappear but shines as Brahma Swarupam. The beginners have to consider the
world as unreal appearance and on attaining the state of Self Realization, the world will appear as the form of Self.
For example the cow, the dog, the world and the people will appear as cow, dog, world and people but all will be in the
form of Self. This is the state of Self Realization. This is different from deep sleep because for a Self Realized person, there
in the sleep there is no Ignorance but only the Self alone.
Arunachala Siva.
