Without Sage, Sri, Sankara there is no Advaita (non-duality). Since it was mixed up with orthodoxy there is a lot of confusion. Sage Sri, Sankara’s quotes (selected verified) are quoted in my blogs and postings to show what Sage Sri, Sankara meant and ‘what is blocking the seekers from realizing the ultimate truth or Brahman.
There are so many non-dualistic masters of the east and also from the west who expound Advaitic or non-dualistic knowledge, but none of them is helpful to reach the ultimate end of understanding.
Sage Sri, Sankara say: Keep the scriptures for children but throw them on the fire for wise seekers.
In Brahma Sutras Sage Sri, Sankara takes for granted, assumes that a world was created: He there mixes dogmatic theology with philosophy.
That God created the world is an absolute lie; nevertheless you will find Sage Sri, Sankara (in his commentary on Vedanta Sutras) clearly says this! He has to adapt his teachings to his audience, reserving the highest for philosophical minds.
The text of Brahma Sutras based on religion, dogmatism, but in the commentary Sage Sri, Sankara cleverly introduced some philosophy. If it objected that, a number of Upanishads are equally dogmatic because they also begin by assuming Brahman, but a few Upanishads do not, but prove Brahman at the end of a train of proof.
The causality and creation, but these are for religious people only. Religion is only for those who are unable to understand truth beyond the form, time and space. Religion is not final. It only gives satisfaction to the populace. The self - knowledge is for the whole humanity to free them from experiencing the birth, life, death and the world as reality.
People of small intelligence follow religion and believe that God created the world. However, how do they know that He did so? When a pot is created, one can see both pot and its maker, but not in the case of the world.
Self-knowledge or Brahma Gnana or Atma Gnana 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 Advaitic truth. Therefore, there is no need to convince anyone other than our ownselves to get a firm conviction.
