Atman or Soul or Consciousness is permanent, and is ever present and only the three states changes. There are no two self. The permanent ‘self is consciousness. And the ego is the false self within the false experience of duality (waking or dream). The way to the Real self is through inquiry and reasoning.
consciousness is ever-present, like the screen on which all three states moves like cinematographic pictures e. While the pictures appear on it, it remains invisible. Stop the pictures, and the screen, which has all along been present, in fact the only object that has existed throughout, will become clear.
All these universes, humans, objects, thoughts and events are merely part of the waking or dream. Waking or dream moving like pictures on the screen of Atman or Consciousness, which alone is real.
Waking and dream pass away, but Atman or soul or Consciousness remains ever. Seeker must distinguish between the ‘true self, and the ‘I’ or ego. ‘I’ am merely an object to Atman. Atman or consciousness is the subject, which witnesses the ‘I’ or waking or dream or universe or duality.
One is born, lives sleeps, wakes up, eats and thinks, dies within the waking or dream. But the Atman the true self is eternal existence, free from ignorance and illusion.
