The unity in diversity is possible only through Self-Knowledge or Brahma Gnana or Atma Gnana not by mastering the scriptural knowledge.

 

 

 Self –Knowledge  or Brahma Gnana or Atma Gnana  is meant only for those who have intense urge, and courage to accept the truth with humility and reject the untruth. Since people start comparing with their scriptural knowledge, it becomes impossible to assimilate and realize the non-dual truth.   Therefore, there is no need to convince anyone other than our own-selves to get the firm conviction. 

Gaudapada says :- the merciful Veda teaches karma and upaasana to people of lower and middling intellect, while jnana is taught to those of higher intellect.

So they clearly indicate rituals and theories are not meant for those who are searching for the higher knowledge or wisdom.  

All the orthodox Advaitins indulge and immersed themselves in ritualistic oriented life style and preach theoretical philosophies which are obstacle in realizing the Advaitic truth.  Many chose these orthodox scholars as their gurus. But these gurus are good to learn the conceptual Advaita meant for those orthodox who believe their conduct oriented life style leads to liberation.  But those who are seeking truth have to do their own homework in order to acquire self-knowledge.

That is why in Ish Upanishads declares  :-

Vidya and Avidya both are hindrances to Self-knowledge, but Vidya is even worse than Avidya. The word Vidya is used here in a special sense; here it means worshipping gods and goddesses. By worshipping gods and goddesses you will go after death to the world of gods and goddesses. But will that help you? The time you spend there is wasted, because if you were not there you could have spent that time moving forward towards Self-knowledge, which is your goal. In the world of gods and goddesses you cannot do that, and thus you go deeper and deeper into darkness.

Avidya is Karma and therefore a hindrance. You perform Avidya - i.e., you perform Agnihotra and other sacrifices. This is a roundabout way of purifying the mind, and it is also groping in the dark. But it may not have as heavy a toll on your time and energy as the other.

Therefore, self-realization is necessary in order to realize the ultimate truth or god.  Self-realization is real God realization.

People are ignorant and they are unaware of the reality of their true existence. Man and his experience of universe is simply a mirage created out of   the consciousness, Consciousness is the real Self, the real Atman, is the reality.

That is why in Mundaka Upanishad indicates: - The rituals and the sacrifices described in the Vedas deal with lower knowledge. The sages ignored these rituals and went in search of higher knowledge. ... Such rituals are unsafe rafts for crossing The sea of samsara, of birth and death. Doomed to shipwreck are those who try to cross The sea of samsara on these poor rafts. Ignorant of their own ignorance, yet wise In their own esteem, these deluded men Proud of their vain learning go round and round Like the blind led by the blind.

 

Sri, Ramana Maharishi said: Scriptural knowledge is conceptual divisions invented by teachers of philosophy by their excessive analysis. Where do all these concepts end? Why should confusion created and then explained away? Fortunate is the man who does not lose himself in the labyrinths of philosophy, but goes straight to the source from which they all arise.

Ramana Maharishi indicated the direct path to the truth, is the source from which the false arises. Thus the source is the soul/ Atman, which is the true self. Atman itself is Brahman.  Thus it is necessary to view the worldview on the base of the source, which the true self, and formless substance and witness of the experience of diversity. Thus deeper inquiry, analysis and reasoning on the true base, one can acquire the Self –Knowledge  or Brahma Gnana or Atma Gnana in lesser time and effort.  The unity in diversity is possible only through Self-Knowledge or Brahma Gnana or Atma Gnana not by mastering the scriptural knowledge.
