Advaitic essence is hidden within the illusion therefore it cannot be got without the inner (mental) journey.

Yoga, Silence, meditation, rituals and devotion are based on the false self and false experience does not yield truth one seeking for, because the truth is beyond false self (ego) and false experience (universe). Mysticism is based on individual experience. The self is not individual because the self, which s in the form of consciousness, pervades in everything and everywhere in all the three states. Blind beliefs without verification and argument and interpretation on the base of false self are not verified knowledge therefore it is not truth.

 One has to go beyond Vedas means go beyond religion. Go beyond religion means, go beyond concept of god.  Thus, going beyond Veda, religion and conceptual god means going beyond illusion.   That is end of Vedas (Veda –antha) .

Sage Sri, Sankara declared: - the world is myth and Brahman alone is real then why to worship the Guru and Gods based on the ego, which is false self within the false world.

 All the karmas performed by the orthodoxy are non-Vedic and barred by Vedas. That is why Veda bars such worships and people who indulge in such activities will suffer and sink into darkness.  And Upanishads says self-realization is the human goal. Therefore, one has to strive only for self-realization or truth realization.     

The yogi and mystics they are based on the conceptual religion, conceptual gods and scriptural authority which are based on the ‘I’ which is false self. People too are not aware of the fact, they do not think beyond the experience of the three states. Therefore, it is very much necessary to verify the facts before proceeding in pursuit of truth, to know whether self is a physical body (waking entity)  or  the soul, the innermost self.

What is it that witnesses the dreams without the physical body?  If the dream is witnessed without the physical body (waking entity or ‘ego’) then what is it that is aware which is not the physical body. Therefore, there must be a formless witness of the dream.   This formless witness is the same witness that that witnesses the waking and deep sleep. Therefore the three states are witnessed by one and only formless witness. 

The three states merge into the mental state, in the sense that when it is analyzed, it is found to exist inseparably in and as the mind alone. All "spiritual" planes are mental: people who regard them as reality are deceiving themselves. 

Yogic or religious truth is individual truth, not universal.  The mystics cannot claim that they have experienced the whole.  There is no proof they have seen it, because the whole is not an individual experience. The man and the world are within the whole.

The Yogi or mystic who sees or experiences something in his meditation, which he takes as the highest is mere individual experience, within the false experience (waking) “whatever is based on individuality is not the ultimate truth or Reality.

 If they say, “they know from experience” they merely assume so.” mystic experience is based on ego thus it is part of the illusion. Self realization is not an individual experience.  The yoga and mysticism are individualized truth. Since they consider the ‘I’ as self they cannot know the Universal self  or  Atman . the Atman is the ultimate truth or Brahman  Atman is present in the form of consciousness.

Sri, Sankara says Atman is Brahman and everything is Brahman is scientific declaration not religious or yogic. Sri, Sankara and Goudpada are more scientific than anyone else in the world. Since, the real Advaitic essence is hidden within the illusion therefore  it cannot be got without the inner (mental) journey.
