Wisdom is for those are capable of inquiring into their own existence to know and realize the ultimate truth or Brahman

This material existence is mere mirage. It is like a wax in the candle it will burn away.  All attempts for freedom is possible only when one is ready to overcome the ignorance. To overcome the ignorance is possible only when one realizes the birth, life, death and the world are mere illusion created out of consciousness.  The consciousness is ultimate truth. And the one who knows this truth knows the knower (soul or consciousness) is free from the known (mind or universe).  

Through Self-knowledge or Bramha Gnana or Atma Gnana, all of one’s egocentric successes and all of his credible accomplishments within the duality are ultimately evaporated and consciousness alone will prevail as nondual existence.

Orthodox Advaita  accepts karma theory.  If one accepts the karma theory, he will not reach the non-dual destination.  If one accepts karma theory then it is impossible to hold the world as illusion. All the pundits’ explanation of karma theory carries no weight,  because karma theory is based on the false self, which is bound by experience of birth, life and death and form, time and space, whereas the true self is formless Atman, which the innermost self. The Ataman is in the form of consciousness, is birthless and deathless because it is formless.

Gaudapada’s rational exposition of Advaita: - that whatever is seen, whether external or internal, whether by the ordinary persons or yogis, is unreal. 

The birth, life death and world are part of the waking experience, which is mere illusion on the standpoint of the formless soul the innermost self  self. The soul is present in the form of consciousness.  It is no use of saying that, we are not born, we do not die because, because we all were born and we all are going to die. However, the birth, life, death and the world are part of the illusion, which comes and goes as waking experience.  The formless substance and witness of the three states is real, which is our true identity.   The Self which is in the form of consciousness has no birth and death. The ultimate truth or Brahman nothing to do with the orthodox Advaita, which claims itself, it is based on Vedas.  But it indulges in worshiping all non-Vedic gods.

That is the way the Upanishads declared Atma Gnana or Brahma Gnana will not dawn by   studying Vedas or indulging in intellectuality.

Buddha, Sri, Sankara and Sri, Goudpada have declared non-dual truth centuries back but one has to reach the destination with scientific(rational) investigation not through punditry and intellectuality. 

One has to mentally reach the final conclusion, than only the conviction becomes firm. Without the firm conviction the wisdom will not dawn. Therefore, there is a need to know consciousness is real all else is a myth, which Sri, Sankara declared as the world is myth Brahman alone is real.

Sage 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 it cannot be got without the inner (mental) journey.

Goudpada says that:- The merciful Veda teaches karma and Upasana to people of lower and middling intellect, while Jnana is taught to those of higher intellect.

Gnana here is knowledge un-contradictable truth or scientific truth. Thus their scientific truth of the whole not the part is declared by Sri,Sankara 1400 years back and thought only to those of higher intellect. Thus karma and upasana, yoga and orthodoxy have to be bifurcated in order to realize the ultimate truth or Brahman.  

Wisdom is for those are capable of inquiring into their own existence to know and realize the ultimate truth or Brahman
