Only through deeper inquiry, analysis and reasoning one becomes aware of the fact that, the formless substance and witness of the mind is the true self.
Only through inquiry, analysis and reasoning on the true base the truth will start unfolding.
v What sees various objects, scenes and persons during the dreams without the physical apparatus?
v If the dream world was without the witness, it is impossible to witness it. Then what witnessed the dream as a whole, if ‘the witness of the dream is not the physical?
Therefore, one has to come to firm conclusion and then conviction through inquiry and reasoning.
The one that witnesses the dream as a whole is also witnesses the Waking experience as a whole, it is also aware of the deep sleep experience. But it is apart from the three states because it is not an entity or identity within the waking or dream.
Man experiences the world within the mind which appears as waking or dream and disappears as deep sleep. Therefore the formless witness of the three states is within the three states as their formless substance and it is without the three states as their formless witness.
Only through deeper inquiry, analysis and reasoning on the true base the nondual truth can be grasped and the formless witness can be traced grasped.
