Scriptural Masters or 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.

Scriptural Masters or  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.

Upanishads:-

Fools dwelling in darkness, but thinking themselves wise and erudite, go round and round, by various tortuous paths, like the blind led by the blind. (Upanishads Nikhilananda -  Ch II-5 P-14)

Upanishad's say "He who thinks he knows, does not know." This means that to know anything implies a second, an object of knowledge, hence duality, i.e. no Gnana.

Second-hand knowledge of the self-gathered from books or gurus can never emancipate a man until its truth is rightly investigated and applied; only direct realisation will do that. Realise yourself, turning the mind inward. – Tripura Rahasya, 18: 89

The pursuit of truth is a mental journey. Deeper self-search  makes one aware of what truth is and what is untruth and the subconscious  will be able to reject the untruth after knowing, what is Truth. Whatever prevails after rejecting the untruth is the ultimate truth.

Pundits have to test truth in this world not in the next world.  There is no proof other then blind belief based on the scriptures, belief is not truth.  So, doctrines are not the means to realize the 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. Seeker reaches a stage 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 self-search 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. 

There is a controversy as to the meaning of Maya. One Advaitic School says it is a shakti of Brahman whereby both illusion and creation are brought about.

How do you know that it is the truth? If one bases it on the sayings of Rishis and saints, granting that they honestly believed in their experiences, there is still the query how do they know that these experiences were the truth?

Even in dream whatever experienced becomes unreal when waking takes place.  Similarly when wisdom dawns one becomes aware of the fact that, the self is neither the waking entity nor the dream entity.  Thus whatever experienced as waking experience is as real as dream.  Thus for a Gnani all the three states are mere mirage created out of consciousness, because he is fully aware of the fact that, the witness of the three states is not the body but consciousness.  A Gnani is fully aware of the fact that, his body, ego and universe are nothing but consciousness. Thus he finds the experience of any sort is play of consciousness and experience is mere mirage.  The one witnesses the experience, which is in the form of universe or mind is mere mirage.     

 Even mentally challenged people believe in what they see and feel and yet their experiences are often quite untrue. What then is it in us, which ascertains the truth of these experiences? If one says it is mystic experience, then everyone’s experience differs from another. Such disagreement does not settle the matter. Thus these are the two common sources—scriptural authority and Yogic Samadhi--but both are shown untenable because both are based on the false self-(waking entity or ego).
