We are discussing about the formless truth in the realm of untruth (duality]) If we rectify the reasoning base from, form to formless, then the words and concepts will become meaningless. To travel from ignorance to wisdom one has to use the words and concepts and as his understanding matures he has to drop them.
Everyone is not in same level of understanding, some are in elementary level and some are in advanced stages. In elementary stages we have to use more words and concepts to make them understand and also to overcome the inherited conditioning, for advanced seekers are sharp enough to understand assimilate the truth with lesser words.
Spiritual pursuit is a very personal journey. Seeker of truth has to bifurcate everything which is based on the ego, (false self), such as religion, god, paths and theories and philosophy.
Seeker of truth should not indulge in condemning religion and yoga or its gurus or gods and its code of conducts. But he has to highlight its fallacy for his own information, which helps him to proceed deeper in investigation.
Seeker of truth has to mingle and discuss with like-minded people but never indulge in arguments about religious doctrines and teachers and teachings and philosophies.
Religion and god and guru glorification and scriptural studies or yoga are not needed in pursuit of truth. Only one must have the intense urge to know the truth and courage to accept the truth and reject the untruth, when un-contradictable truth is revealed through inquiry analysis and reasoning.
A receptive mind free from religious and yogic or any sort of knowledge based on the ego is very much necessary to acquire the non-dual wisdom.
All the accumulated knowledge from religion and yoga and paths and theories are mere dross in pursuit of truth. Religion and yoga are helpful for the mass and the society but they are barricade in unfolding the mystery of the mind.
Even in the Buddhism: - Buddhist teaching has itself become a kind of interactive and self-evolving process, much like its idea of pratityasamutpada. However, the end goal is still Nirvana, which is an experience ultimately beyond all concepts and language, even beyond the Buddhist teachings. In the end even the attachment to the Dharma, the Buddhist teaching, must be dropped like all other attachments. The tradition compares the teaching to a raft upon which one crosses a swift river to get to the other side; once one is on the far shore; there is no longer any need to carry the raft. The far shore is Nirvana, and it is also said that when one arrives, one can see quite clearly that there was never any river at all.
The scriptures and theories and teaching based on the ego are not the yardstick. Using them as yardstick to understand and assimilate the truth will lead one towards pursuit of arguments. Seeker of truth has to discover on his own, the truth of his true existence by inquiring “what is mind?” and “what is substance of the mind?” and move forward.
The wisdom consists in knowing the truth, that everything [mind or physical existence] is consciousness. Freedom (truth) is always there yet one does not know it. But to those whose reason is turned away from physicality and who have attained the serenity of the soul/self (consciousness) are quite near to the ultimate truth.
To think one's own body and his experience of the world is an illusion is difficult matter, unless one realizes the self is not physical but it is formless soul, it is difficult to have glimpse of the non-dual truth.
When one realizes the fact that, the self is not physical but the formless soul, naturally the body and universe becomes illusion.
The mind (universe) is emanating from soul (consciousness) means the mind is being effect from consciousness is not different from it. Deeper analysis shows it. Analysis needs deeper thinking and reasoning. Mind is whole universe thus it has a form. But where is the form in consciousness (soul) because consciousness is like an ocean and mind is like wave. The universe is same consciousness, as the ocean produces the wave, so the consciousness produces the mind (universe).
The moment one knows the mind (universe) is consciousness, and then there is no ignorance. If one knows consciousness as self then everything is consciousness, the consciousness is second to none. The mind is consciousness but due to ignorance one mistakes it for something else. One thinks the self is within the body; but the self is without the body and the world.
Mind ceases to exist without the matter. Without the matter mind ceases to exist as mind but it exists as matter- less awareness or consciousness. Without the mind neither the world nor its perceiver can exist.
Without the matter there is no duality. Without duality there is no experience. Without experience it is non-dual reality. Therefore, whatever prevails without the mind is ultimate reality.
The true nature of the soul (consciousness) is camouflaged by the illusion/duality/universe. To know the truth one has to discover and realize the formless substance of the mind or illusion. One has to learn to view and judge the worldview on the standpoint the formless soul as self. Self-Knowledge or Brahma Gnana or Atma Gnana is the prime goal of the truth seeker. This goal is hidden within the mind as its invisible substance and witness. Therefore, it is necessary inquiry, analyze and reason in to the nature of mind/ duality/illusion/universe in order to unfold the mystery of mind or duality or illusion.
