All divisions, which are named, are also consciousness.

  There is no need to name and create division and try to understand and assimilate the ultimate truth. On the ultimate standpoint everything is one. All divisions, which are named, are also consciousness. So, there is no second thing exists other than consciousness. Consciousness is ultimate truth or Brahman.

Many believe spirituality and religion are considered inter connected but it is not so. Religion is based on the false self-(ego or body) and it is limited to the false experience [universe], while spirituality transcends race, religion, gender, language and nationality and universe. Spirituality is pursuit of truth. 

There are many paths have come into existence in the name of Self-Realization.  Every belief system believes that each human being embodies a spark of the divine, and that fanning into the shining fire spiritual realization is the meaning and purpose of human life. But spirituality is not based on the belief but discovering the truth of the whole universe and man’s existence. Religious and Yogic truth and scientific truth are individual truth based on the false self(ego) within the false experience. Individuality has no value in the realm of ultimate point of view. Therefore, realization of true self is necessary in order to realize the ultimate truth, which is free from all the diversity, which is present in the form of universe. The universe ceases to be real from the ultimate point of view. The ignorance is the cause of experiencing the unreality as reality. Therefore truth realization is necessary to unfold the mystery of the universe, which appears to be real from the physical point of view.

Universe is reality on the base of ego, which is the false self. It is unreal on the stand point of the consciousness, which is the true self. Universe is mere mirage from the ultimate point of view. Man perceives the world within the universe; therefore his existence is limited to the universe, which is in the form of mind.

Consciousness is real because it is permanent, but universe, which is in the form of mind, appears as waking or dream (duality) and disappears as deep sleep is impermanent (non-duality). Thus mind is not absolute and eternal like consciousness itself. People stuck with the reality of the world, so they take it as real. Once they take their physical existence to be real then they have accepted the false self as real self and false universe as reality. Thus their judgment is based in the false self, will keep them within the threshold of duality. Thus the ultimate truth lies beyond duality.

People take the universe confronting them as real, the experience of birth, life and death, which happens within the universe, which they experienced as reality. When the self is not physical but self is formless, then whatever seen, known, believed, experienced as person within the universe is falsehood, on the base of the formless self (witness).

The gross universe is merged into the mental universe in the sense that when it is analyzed, it is found to exist inseparably in and as the mind alone. All "spiritual" planes are really mental: those who regard them as different or higher will remain ignorant.

A Gnani is free from experiencing the illusion (body + universe) as reality, he is fully aware of the fact that, his body and his experience of the world as consciousness, which is ultimate truth. 

People who are incapable to inquire and reason are tending to follow some philosophy without verification. Therefore the more ignorant they are the easier to get them into a religious fold. Religion is so strong and popular because it makes no demand on the intelligence and it simply requires belief in guru and his teachings. 

It never strikes believer to doubt whether his inherited belief system is true. They never use their reason because they start and conclude that their belief system alone is true, because they never question the validity of their inherited belief. 

For religion one can interpret texts as he likes, in whatever way that pleases him, he simply imagine away. The idea of god injected in the past and inherited by people and they refuse to verify the facts, because they think it blasphemy even to question their inherited belief system.

In pursuit of truth the ultimate truth has to be proved, not assumed. Pundits who take scriptures for granted are not Gnanis.

Pundits teach that all is your-self, but none of them can show that this is so, none has analyzed it scientifically, and none can prove it. Rational proof is needed, so that one arrive at knowing truth i.e. wisdom; punditry is mere dogma, parrotism, repetition of what they read in scripture. Scriptures are not yardstick and scriptural truth is not proof. Pundits take scriptures as authority. Authoritarianism merely assumes as true what another says, but what has yet to be proved.

Pundits have to test truth in this world not in the next world. There is no proof other than blind belief based on the scriptures, belief is not truth. So, doctrines are not the means to realize the ultimate truth. There is no need to follow them. 

Doubts and Confusions arise when seeker finds the scriptures and yoga are inadequate or useless to quench his spiritual thirst. Disappointments in religion or yoga or even science imply error or ignorance.

When serious seeker reaches a stage with all his baggage of accumulate knowledge, then uncertainty haunts him. Whether he is right?" Where is the certainty that he is proceeding on right lines?" Thus doubts arise and the inquiring spirit comes and impels to search elsewhere for truth where it will not be possible even to have doubt. The test is therefore in experience. And only in non-duality, where there are no two to argue about views or to have difference of opinion can such doubtlessness be possible. Belief depends upon unstable bases whereas certainty depends on proof.

Seeker of truth has to get rid of his doubts through deeper inquiry, analysis and reasoning on his own, to realize the fact that, the self is not the form but self is formless. Thus his analysis and reasoning has to be based on the formless not on the form. By simply go on believing and accepting whatever said by the punditry will not lead one towards path of wisdom. All the doubt has to be got rid of "by the sword of Self - Knowledge." The scriptures, yoga are not necessary if one follows the inner (formless) path. Religion and yoga are not the means to path of wisdom.

They alone in this world are endowed with the highest wisdom who are firm in their conviction of the sameness and birthlessness of Atman. The ordinary man does not understand their way. [Chapter IV — Alatasanti Prakarana 95-P-188 in Upanishads by Nikilanada]

This passage indicates the fact that everything is soul or consciousness  or spirit. The one who views and judges the worldview on the base of his birth  or body will not realize the fact that, the man including the world is created sustained and finally dissolves as soul or conciousness. Thus Atman alone is, and all else is mirage.

Thus Self-Knowledge or Brahma Gnana or Atma Gnana  is the aim of every human being. Since everyone thinks the physical body is the self, their aim is misdirected and they focus their attention on materiality which makes one feel the duality (waking) as reality.
