Without mentally rectifying our reasoning base from form to formless it becomes difficult to assimilate the Self-Knowledge or Brahma Gnana or Atma Gnana. It takes some time to sink in. There is no need to even to discuss in length, if one goes on reading my blogs:-
One will find answers for all his doubts and confusions. And as his conviction becomes stronger by becoming aware of the fact that, the self is not the form but the self is formless, his reasoning base also will be rectified mentally from form base to formless base.
There is no use of taking strain to understand assimilate the conceptual divisions invented by teachers of philosophy by their excessive analysis. There are more and more doubts and confusions, if one tries to understand and assimilate the ultimate truth through scriptures.
Why to follow the path of doubts and confusion by losing oneself in the labyrinths of philosophy, when one can realize the ultimate truth without them. By mentally tracing the source of the mind from where it rises and subsides one becomes aware of the fallacy of the mind, which rises as waking or dream and subsides as deep sleep. The mind raises form consciousness and subsides as consciousness. Therefore, there is a need for perfect understanding assimilation of non-dual truth.
There is no need to renounce the worldly life to get Self-Realization. Any householder can attain it if has the inner urge and sharpness to grasp.
Mind is universe, because when the mind (I) is there then only the universe is there. The ego, body, universe appear together and disappear to gather. Limiting the mind (I) to the physical entity is cause of the ignorance. The body, ego, universe ceases to exist without the mind. If one of these is absent then the mind is also absent. Thus mind is the whole universe, which appears as waking or dream(duality) and disappears as deep sleep(non-duality) Thus one which is aware of the appearance and disappearance of dual and non-dual experiences is not the form(body or ego) but formless(consciousness).
The consciousness (soul) is the true self. The true self is the source of the three states. These three states deceive; the people fail to look beyond them to its source, which is real, supreme and imperishable. The three states are mere mirage/illusion. It is difficult to overcome the illusion without the wisdom. But one can cross over this illusion, by realizing and becoming aware of the fact that, the self is not physical but it is consciousness.
People are deluded by illusion, because they have immersed in the illusion experiencing it as reality. They are ignorant because they think the self is physical and birth, life, death and world as reality. Having lost all discrimination, they follow the way of their physical nature. When ignorance vanishes through wisdom then only it is possible to negate the illusion, the mortal becomes immortal. When all the physical shackles that strangle the self are loosened, the mortal becomes immortal, here in this very life.
The ultimate understanding is: Nothing has actually been created. All that appears is mere mirage. Everything is consciousness and nothing can be a part of it. No second thing exists other than consciousness, neither the man nor the world, which contains all the objects exits in non-dual reality.
The duality means the mind, which is in the form of universe. The universe appears as waking or dream. Man and universe co-exists together within the waking or dream. When one analysis deeply, then one becomes aware of the fact that neither the waking entity nor the dream entity is not the self. But the self is without these three states. That means the self is formless and apart from these three states.
None of these three states can exit by itself alone, without this formless self, who is within the three states but it is apart from these three states. It is within because it the formless substance and witness of these three states. It is apart because it is not an entity or identity within the waking or dream. The three states are impermanent in their nature but the self, is formless substance and witness of the three states is permanent and eternal. The self can exist with or without the three states. In deep sleep it exists without the waking or dream experience. Thus it is empty of duality. Thus the emptiness is the nature of the true self, which is in the form of consciousness. The consciousness is aware of these three states, which appears as waking or dream and disappears as deep sleep. By becoming aware of the existence of formless self mentally one becomes aware of the fact that, the three states are mere mirage created out of consciousness. Thus three states are mere mirage that has to be transcended by tracing the formless substance and witness of the three states, which is in the form of consciousness.
Once one gets the firm conviction that the consciousness is the true self then the wisdom dawns and the through wisdom one becomes fully aware the universe, which is in the form of mind and soul or self, which is in the form of consciousness are one in essence. Thus the mind (universe) becomes one with the soul (consciousness). Thus no second thing exist other than the consciousness. Therefore, consciousness alone exists as ultimate truth, the universe or mind is mere mirage created out of consciousness.
