The Ultimate Understanding is to understand there is no second thing exists other then the soul" and the whole diversity is created out of the soul which is in the form of spirit or consciousness.
Whatever is known, seen, believed and experienced is mere mirage created out the soul/self. Thus everything within mirage is the soul/self.
The acceptance to accept the diversity as mirage happens or not is the Will of soul, which is the true self. And it is not the destiny of the individual concerned, because individuality is mere illusion. Thus one who believes in past, present and future and rebirth and reincarnation is not fit to receive the self-knowledge because he accepts the individuality as reality. Without making sure of the fact that the individuality is mere mirage through deeper inquiry, analysis and reasoning it is impossible to come out of individuality. The reason based on individuality produces intellectuality. Intellectuality is not the means to self-knowledge. There is no end to argument based on intellectuality because it is based on the false self/ego.
It is impossible to “kill the ego" alone because the body, world and ego appear together and disappear together. All preaching, practices and writings are base on the false self /ego which leads to lots of doubts and confusion. The ego bases itself intellectuality and intellectuality is I based on individuality. Thus individuality cannot transport one to the nondual destination. Thus, ornamental words may satisfy the ego but it has no value in pursuit of truth. The ego alone cannot be converted back to the stuff from which has been created.
The individual experiences are not realization because the individuality is part of the mirage. The individual experiences are happenings with in the mirage, thus the personal experiences are of no value in pursuit of truth. The one who knows the formless substance and witness of the mirage knows “What is truth? is and “What is untruth”. Thus he has mental yardstick or wisdom of judging what is real and what is unreal.
"Events happen; deeds are done by an individual, but all that has taken place within the mirage. There is no individual doer because the whole experience of diversity is dependent on the soul/spirit." Until one learns view and judges the three states on the base of the soul, he will not realize the he and his experience of the world is mere mirage. Without realizing the mind as a mirage he will not be able to accept the individuality as mirage. Until once judgment is based on the individuality the truth will not be revealed, and it is impossible to move towards universality.
The main confusion arises only when one thinks he is person born in this world and the world existed prior to him; until this conviction is there it is impossible to assimilate nondual truth. Thus it is necessary to realize the fact through deeper inquiry and reasoning the body is not the self and self is not born. Therefore, it is erroneous to treat the body as self and judge and conclude the truth on the physical base/ego.
Many seekers want to know and realize the truth but they are stuck with their inherited idea of karma, rebirth, sin and reincarnation and heaven and hell. All this ideas are based on the physical self. When the self is unborn the karma, rebirth, reincarnation theory itself has no value.
With what one is able to perceives the world as person? Why the person and his experience of the world cease to exist without the waking experience? Where the waking experience disappears when the dream appears? Where the ego, body and the world exist?
Self-realization is simply the realization of the fact that, the true self is apart from the three states. True self is nothing to with the physical entity and the world which present only in waking or dream. The ego is nothing to do with truth. Whatever is based on the ego is falsehood because the ego is present only within the false experience.
The formless substance and witness of the three states is the soul is the true self. On the standpoint of the soul as self, the all the accumulated intellectuality is falsehood. Thus, arguing on the base of intellectuality, which is based on the false self /ego, is not of any value.
