It is necessary to repeating the same truth again and again till it becomes reality. One needs to constant reflect on the subject until he gets a firm conviction of what is what. Words are needed until one gets firm conviction of ‘what is what’. People need reading and hearing the words to think deeply and reach the ultimate end.
In deeper self-search:- When one realizes the existence of the formless witness of the three states is apart from the three states then he realizes that, it's not the waking entity which is witnessing the three states but the formless soul, is the witnesses the coming and going of the three states.
The soul, the innermost self is present in the form of consciousness. Thus the formless soul or consciousness is the knower or the witness of the coming and going of the three states. The soul, which is present in the form of consciousness, is real eternal.
Yoga cannot yield non-dual truth because everything that yogi does or practices and experiences within the ‘known.' Yoga yields relative truth, i.e. true from a particular viewpoint, not ultimate truth.
Man and all the objects of the world within the waking or dream are known and passing away every moment, hence unreal. Hence we ought not to get attached to the passing show. Not only we individuals will change and die, but empires and the mountains and the population will disappear with the waking or dream.
The Seeker has to start with the mind which is present in the form of the matter. He has to analyze the mind and taking away from it all those portions which are ever changing or passing, he becomes aware of the existence of the formless witness of the three states, which is ever-changing.
When a seeker is able to make the distinction between formless witness and the three states then he will be able to realize “what is truth” and “what is untruth”. The formless soul, which is present in the form of consciousness, is present everywhere in everything in all the three states.
There are two factors to remember: -the knowing capacity and that which is known. The three states are known, and they are all passing away and are therefore unreal. Without the knowing capacity i.e. the knower or the witness in existence there could have been no such thing as knowing these things. Knowing implies two factors, the knower or the knowing capacity, or that which becomes aware; and the known. Without these two factors one cannot use the word know.
The known (three states) always passes away in succession. When one is able to distinguishing between knower and known, he becomes aware of the fact that, the subject is the formless soul (knower or witness) and the object is the three states. When waking and dream disappears, the formless soul, the innermost self alone prevails as eternal existence.
The non-dualistic or Advaitic truth is always real. Reality does not exist with forms and names and feeling. That which underlies these is the reality. Reality underlies limitations, being itself limitless. Reality is not bound. Reality underlies unrealities, itself being real. The reality is that which is. Reality is as it is. Reality transcends speech. Reality is beyond the expressions `existence, non-existence.
The reality which is the mere consciousness that remains when ignorance is destroyed along with knowledge of objects, alone is the Self (soul). In Self-awareness, there is not the least ignorance.
