The soul,which is present in the form of consciousness is ultimate truth or Brahman or God. The consciousness is hidden within the mind. The mind is present in the form of universe. The universe rises waking or dream and subsides as deep sleep.
Individuality is mere illusion on the standpoint of the soul or consciousness as self. All individual experiences are happenings within the mind or universe are mere illusion. Therefore the experience of birth, life and death which takes place within the illusory universe are bound to be illusion. the illusion is created out of consciousness. The illusion [mind] appears as waking and dream and disappears as deep sleep [soul].
The soul or the consciousness is the formless source of the illusion from where the mind rises and subsides. The consciousness is also the formless substance and witness of the illusion. Therefore there is a need to find the source of the mind to realize the formless source, which is the soul or consciousness. The soul or consciousness is the innermost self. On the standpoint of the source the three states are mere mirage created out of the consciousness. Thus, there is no second thing exists other than the source, which is consciousness.
The source of all problems is the mind. If mind is there all the problems are there. Therefore, there is a need to understand and realize “What is mind?” "What is the substance of the mind?" and "what is the source of the mind?', in order to discover the un-contradictable truth.
The nature of truth is to be free from contradictions. As one approaches nearer and nearer truth as he finds less and less contradictions. The only thing which is so free is the formless soul, the innermost self. 'This may be achieved at first, in lightning flashes, in fleeting momentary glimpses, but later this must be established into permanency. One should stabilize them through constant reflecting on the nature of the true self, and through the constant reminder that the mind (universe) is not separate from consciousness, which is the true self.
It is not enough to grasp the intellectual truth of non-duality'...'As the man of realization knows the three states are mere mirage created out of the soul, which is in the form of consciousness and he knows there is no difference between mind and soul because the mind and the soul are one in essence. that essence is consciousness. He knows the truth of universal self-identification. Any kind of difference means contradiction. And in duality there is always contradiction. But in non-duality there is no second thing exist other than the consciousness. If one thinks there is another entity, whether man or God, there is no truth. The consciousness is ultimate truth.
In the soul or consciousness in which the mind (waking or dream) rises and subsides like waves in the ocean.
There is no benefit of exerting mental effort on the base of ego. Thoughts arise, one identifies with his thoughts and this, then, defines his experience. But he is ignorant of the fact that, the thinker and the thoughts and the world are within the mind, which appears as waking or dream and disappears as deep sleep. the thinker,thought and the world are one in essence. that essence is consciousness.
So many thoughts arise and one is lost in them obsessed with them without him even knowing it. So many worries and troubles constantly arising and repeating, and though he may not be aware of all of them, he is none-the-less identified with them. The thoughts will not rise without ego. The ego is present only when the body and the world are present. The body and the world are present only when the mind is present. The mind is present only when the waking or dream is present.
When the consciousness is identified with the physical body then the birth, life, death and the world are reality. When consciousness remains in its formless non-dual true nature then the birth, life, death and the universe is mere mirage created out of consciousness. Therefore, it is necessary to realize the fact that, the self is not physical but formless to understand, assimilate and realize the non-dualistic or Advaitic truth.
