When the self is not the waking entity than what is it that witnesses the dream.

When the self is not the waking entity than what is  it that witnesses  the dream.  If the ‘self’ is not the dream entity than what is it that witnesses the waking experience as a whole?  If the ‘self’ is neither the waking entity nor the dream entity than what is that was aware of the deep sleep. 

All the three states are mental in the sense that when the three states are analyzed, they are found to exist inseparably in and as the consciousness alone.

All "spiritual" planes are really mental. Religion is individualized truth”; Self-Knowledge or Brahma Gnana or Atma Gnana is universal truth.  This means religionist takes the belief as truth whereas the Gnani takes his reasoned judgment, which will be the same under test everywhere in the universe. 

No one has seen God. They do not know God’s capacities, what He can do, and what he cannot do. Therefore any statement one might make about God would only be a lie. God is only a settled fact for believers, but for others His existence is problematic. It is impossible to prove the existence of God by any reasoning without belief system. Every belief- system has its own idea of god and idea of creation. Without belief the God ceases to exist. One must take rational position in order to unfold the mystery of his true existence. Thus the seeker of truth does not know whether God exists or not. He starts his quest without belief and belief system. 

Unless one gives up the religious ideas of individual god, karma, sin heaven and hell, self-knowledge or Brahma Gnana or Atma Gnana is impossible. Truth must be proved here and now, on this very life. If that cannot be done, one cannot consider any such idea, as existence of individual god, karma, sin heaven and hell, as true.

People see visions of Gods and Goddesses and adepts according to their own inherited samskara or conditioning. How does one know that God who tells about himself in meditation or vision is truthful! He may tell you a lie! His statements must therefore be tested. Supposing a mystic has a vision, which experience is true, but he must prove that it is really what it purports to be, and that he is not deluded. 

When the self is not the waking entity than all his claims of seeing God or talking to God as waking entity is bound to be falsehood, because the waking experience itself is falsehood. If the three states are illusion created out of the formless soul or consciousness, the innermost self, than all the visions are also mere mirage created out of consciousness. 

 Only in yogic paths such visions of God and saints are taken as reality because yogis’ approach is more practical, and they are stuck with the reality of the waking experience, and they take it as real.

That is why Buddha said:-   

Believe nothing because a wise man said it,
Believe nothing because it is generally held.
Believe nothing because it is written.
Believe nothing because it is said to be divine.
Believe nothing because someone else said it.
But believe only what you yourself judge to be true.

-Buddha

Authoritarianism merely assumes as true what another says, but what has yet to be proved.  One may believe in a position, but he is required to prove the truth of his belief. A belief is a feeling, truth is knowledge. 

Looking to all these diverse idea of every belief system Create the doubts and confusion. "Which belief system is the right and which belief system is wrong?" .There is the certainty that he is proceeding on right lines if takes path of belief?" 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 reasoning. Only through soul-centric reasoning one can reach the ultimate end of understanding. If one is soul-centric than there is no scope for argument about views or to have difference of opinion and one is in the realm of doubtlessness. 

If one seeking truth nothing but truth than he should not accept anything as truth without verification.
