It is not only the physical body alone exists the whole universe exists together. Science and religion bases their theory based on the birth, life and death; there is an unknown aspect. Thus they view and judge and conclude on base of waking entity. Thus the whole truth is not revealed. Even when all physical measurements are exhausted by the modern science there still remains the mysteries of mind and life-activity.
Science does not really know that the man can exist without the world or vice versa. Therefore the truth is one can never know the origin of the universe without knowing origin of the mind or ’I’. Only suppose and guess work is not the truth. For practical purposes science is very useful for making the life easier, but in pursuit of truth for science is unjustifiable, because pursuit of truth is completely a mental journey beyond physicality.
The contradiction of universe as illusion is in thoughts and occurs when it is resolved into consciousness. Existence is meaningless without non-existence; hence one can neither say universe exists or not exists.
Our forefathers they are no more entities now. The ruined townships of the ancient world, if one carefully analyze, the world and persons of the past are now mere memories. Similarly one thinks he has the same physical body as yesterday but that is only his illusion, his imagination. Yesterday's body has disappeared already. If one sees anything it is bound to pass away.
How is it seen?
By the consciousness.
Therefore, consciousness alone produces ideas of world. Seeker has to realize the fact that, all things pass away, that just as dream world passes away, waking world also passes.
At the first stage of human life, everyone is a realist. One feels pain, and enjoys the pleasures of life and accepts its reality. The second stage is to inquire into the nature of one’s experience.
Such inquiry leads to the discovery of its unreality. But people do not worry about truth? They do not want inquire. They want to find satisfaction in the physical world.
If possible All the 24/7, seeker should be reflecting on the subject. Every object one sees, seek to know the truth about it, not mere appearance to make sure the objective awareness is possible only in waking/dream. The waking/dream appear and disappear thus they are impermanent in their nature.
Millions of creature and animals and human beings suffer and die annually. Why! Where is the benevolent God in all this? What is its meaning? Only wisdom alone one gets replies satisfactorily.
The physical entity, world, Himalayan Mountains disappear along with waking and dream. Thus all form in the waking or dream dissolves as consciousness, which is the source of the waking or dream from where it has erupted.
Discrimination between Self (soul or spirit or consciousness) and Non-self (mind or waking or dream) is the first step in pursuit of truth. Begin by analyzing the physical body: the same applies to the universe.
The birth, life and death are part of the illusion. Thus until and unless and until one makes sure, on what standpoint the birth, life and death are illusion. Without analyzing it one experiences duality as reality.
Till man thinks as a man, the duality will prevail as reality, and he is bound to believe the birth, life and death as reality. And he views and judges and concludes everything on the base of his birth entity, which is part of the illusion. Therefore there is a need to know the fact that, whether the physical body is the true self or the soul (consciousness)is the true self.
If one proves the body is the true self, and then one can take the birth, life and death are reality. If physical body is not the self, then the birth, life and death are mere illusion. Thus one has to know, the one knower of the illusion(birth, life and death) to unfold the mystery of the existence. Searching for the knower mentally will lead one to realize the fact that the consciousness is the true self. And the consciousness is the formless substance and witness of the three states (illusion).
