Blinded with the illusion very few grasp the non-dualistic or Advaitic truth. Only few escape from the web of illusion, only few seekers are able to acquire non-dual wisdom.
waking experience (form) becomes oneness in deep sleep and (formless or oneness) deep sleep becomes waking or dream. Therefore, that which becomes diversity (form), and that which becomes Oneness (formless) is not our physical entity, because the physical entity is present only in waking and dream. The one, which is aware of all the three states, is formless, apart and eternal which is the soul. the soul is present in the form of consciousness The soul or consciousness itself is ultimate truth/Christ/Brahman/Buddha.
The Soul, the innermost self is neither the body, nor the mind, nor the intellect, nor the world. The Soul, the innermost self is neither the breath, nor the heart. The true nature of the Soul, the innermost self is object-less awareness. The experience of duality is mere mirage created out of the Consciousness. Thus there is no second thing other than the consciousness Therefore, holding anything else other than the soul, the innermost self as God is ignorance caused by illusion. The one which powers the illusion is the consciousness. The formless soul or consciousness is real God.
We are discussion about the truth or god within illusion. We argue discuss about the ultimate truth or Brahman within the illusion. In reality there is nothing to argue, nothing to judge, because there is nothing exists other than the formless soul or consciousness.
Upanishad declare:- The human goal is to acquire Self-Knowledge and they indicate the personal gods, scriptures, worship and rituals are not the means to Self –Knowledge, then why anyone should indulge in it. The religion, concept of individualized god and scriptures are greatest obstacle to realize non-dual truth or self-realization, because they are based on false self. Therefore, one has to search the ultimate truth without losing himself in the labyrinths of philosophy, he should indulge in deeper self-search and assimilate and realize it.
The Seekers goal is towards Self-knowledge or Brahma Gnana or Atma Gnana and noting other then it. Therefore, guru is needed in religious and yogic paths, path of love, path of humanity which are meant for the people who are not searching for truth but they are searching for worldly comforts and temporary peace in this physical existence. They fear of losing their physical identity and all that is connected to the physical identity. When one realizes the physical identity (ego) is false self and the true identity is the soul, which is in the form consciousness, then he realizes that the fear factor is limited to the false self within the false experience. When the self is not form but formless consciousness all the burden and bondage of the duality is mere mirage created out of consciousness.
Thus perfect understanding and assimilation is required for realization of the truth. Whatever One has read, heard and accumulated as truth has to be verified through deeper self-search. Nothing has to be accepted as truth without verification.
Self itself is the guru and guide. And the disciple also is the self ; therefore there is neither guru nor disciple, nor teaching because everything is self, which is in the form of consciousness. Consciousness is ultimate truth.
