'Self 'or 'Brahman' cannot be experienced because it is prior to any experience

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

In pursuit of truth,  the ultimate truth has to be proved, not assumed.  The individual experience bliss is not Brahmic bliss or Atmic bliss.

Individual truth is not universal truth.  Individual cannot claim that he has experienced the whole.  There is no proof he has seen it, because the whole is not individual experience. The man and the world are within the whole.  Therefore  such claims of experiencing the soul, the innermost self  is mere hallucination because the whole cannot be experienced because the experience of  the form,time and space are mere illusion created out of  the formless soul or consciousness.  

All claims of experiencing  ( anubava) the 'Self' or Brahman   is falsehood because experience implies duality and duality is falsehood from ultimate standpoint.  Thus 'Self 'or 'Brahman'  cannot be experienced because it is prior to any experience and there is no second thing exists other than consciousness.  'Self' has to be realized by getting rid of ignorance.   

All the physical based theories of creation and creator,  karma, individualized God, rituals, code of conducts   are for the people who are unable to think and reason deeply.

 

There are many schools of thoughts, which are based on waking entity or ego , and they introduced many theories, which are accepted by the mass. But all these thoughts and theories are meant for the mass. Not for those who are seriously seeking truth. 

 Advaitic sages hid the Self-Knowledge or Brahma Gnana  , so it cannot be acquired by studying Vedas or comparing with any other scriptures of other religion, but only through deeper inquiry, analysis and reasoning, it has to be discovered and realized.  

Until one becomes aware of the fact that, the man and his experience of the world are reality only on the base of the false self [‘I’], and man and his experience of the world is illusion on the standpoint of the soul, which is the true self.  

Causality taught in the Upanishads is only to enable us to understand the supreme truth of no-origination. The world is not different from the self and the self is not different from Atman and Atman is not different from Brahman. That the non-dual absolute appears as the diverse world is only an illusion. If it really became diverse then the immortal would become mortal.

 The dualists who seek to prove the origination of the unborn, by that very enterprise try to make the immortal, mortal. Ultimate nature can never change - the immortal can never become mortal and vice versa.

 Gaudapada quotes from the Upanishads: "There's no plurality here"; "The Self through its powers appears to be many"; "those who are attached to creation or production or origination go to utter darkness"; "the unborn is never reborn, for who can produce it?".

Only through  Self-knowledge one is able to understand what Brahman is.  The ultimate truth is beyond religion, God and scriptures.  The self –knowledge is possible only when one thinks beyond religion, scriptures and belief of God. Thus, comparing Vedas with Koran is not the yardstick to make any religion great or meager. 

Only through self-knowledge or Brahma Gnana or Atma Gnana ,   one will be  able to understand and assimilate and realize the fact that, the birth, life and death, rebirth, reincarnation are reality on the base of false self. 

On the base of the soul, which is the true self they are mere illusion.  Therefore, it is necessary for one to understand and assimilate: How the world is not different from the self and the self is not different from soul or consciousness and soul or consciousness  is not different from Brahman. That the non-dual absolute appears as the diverse world is only an illusion
