The pleasure and pain are individual experiences happening within the waking experience. Therefore their reality is limited to the waking experience because the waking experience itself is illusion. Until one become aware of the fact that: how the waking experience is illusion, he is bound to experience the duality as reality. The individuality and individual experiences happening with in the waking experience, is nothing to do with the formless Soul, which is witness of the three states.
The pleasure and pain of the dream becomes unreal when the waking takes place. Same way for a Gnani the waking experience becomes mere an object of experience because he is soul-centric. Most of the god men are pretending to be Gnani but they are egocentric. When one becomes soul-centric for him body and world are also consciousness. Because people think the body is born, lives and dies they feel the pleasure and pain as reality. But it is not body alone that dies, the world also dies together, because they appeared together and they disappear together as deep sleep or death. The one which is aware of the appearance disappearance of the three states is birth- less and deathless soul, which people call it as as emptiness.
The emptiness is the nature of the soul or consciousness, which Buddhist called as nothingness or emptiness and Sage Sri, Sankara called it as Brahman, Meher Baba called it as I AM GOD STATE, and Christens called it Christ consciousness. When one consciously becomes aware of the emptiness s is the true self, then there is no physical apparatus and world to experience, because a Gnani is aware his body and the world are also consciousness. To get this conviction one has understand the fact that, the birth, life, death and world are mere mirage created out of consciousness. Whatever prevails without the mirage is ultimate truth, which is consciousness.
If the self is formless then diversity is mere illusion. One has to know this fact intellectually first, then gradually as conviction becomes firm then he becomes soul-centric and he sees the sameness in everything and the mind reaches the stillness and he becomes aware of the fact that, the soul itself is the ultimate truth.
We all including the world exist in waking or dream. We experience different experiences as individuals. When we consider we are individual separate from the world, we will think whatever is happening within the waking experience as reality, because we are judging the truth on the waking entity, which is erroneous. The waking entity is limited to the waking experience alone. We have to learn to judge truth on the base of the formless knower of the three states. Therefore, the individuality and individual experience is nothing to do with the self, which is formless. Until one includes the world in his realization to grasp the ultimate truth is impossibility.
We have to realize Individual experience of birth, life and death is nothing to do with the true self which is the soul, because the soul is our eternal identity. On the base of soul as self-there is neither witness nor witnessed, there is only oneness.
