Shankaracharya
Said by the BKWSU to be the founding father of the Sanyasi or Renunciants Religions, known to the rest of the world as Adi Shankar an the Indian philosopher of around the 8th century AD, who founded Advaita or "non-dualistic" Vedanta.
He left commentaries on the trilogy of Vedantic scriptures, i.e., major Upanishads of around ten in number including the "Brihadaranyaka Upanishad", the "Chandogya Upanishad" and the "Mandukya Upanishad", the "Brahma Sutra", and the "Bhagavad Gita". He is also said to have written, among others including the "Vivekacudamani (Discrimination of Jewel)", where he fully expounded Vedantic principles, and the "Atmabodha (Self-Knowledge)", where he exclusively discusses the identity between Atman and Brahman.
Shankaracharya exclusively advocates that the real, experiential knowledge of the Brahman/Atman identity is sufficient for the individual to become enlightened and that as far as spiritual seekers are ready to sacrifice everything to obtain this supreme wisdom, they need neither rituals nor meditation as spiritual exercise. He utilised extensive dialectic discussions to dispel almost all arguments made by his opponents. His use of logic was inexorable and in depth.
To his opponents, who ask him why "One", the Brahman/Atman identity, becomes many, this phenomenal world and all living beings with it, Shankaracharya answers that it is because of our lack of knowledge which makes us "superimpose" the false on the real and believe that "one" looks many.
A classical example was supposing that a man thinks that there is a snake in the wood, but in fact it is simply a rope. In this case, as far as he continues to superimpose the false image of a snake on the rope, he will never be able to know that it is a rope. But as soon as he drops the false knowledge, he can experience the reality as it is. Similarly, because of the false knowledge about our real identity, we misunderstand that there is a phenomenal world "out there", which is different from us. It is those who can get rid of this false "superimposition", who will know instantaneously that we are one with the whole world, and that we are "enlightened" already here, at this very moment.
BKWSU view
The BKWSU teach that Shankaracharya was a founder of a new religion and as such was two souls incarnate in one body. One the experienced "chariot" soul, the other the possessing or channelled spirit and founder of the religion.
Further they teach that neither soul gained enlightenment, liberation or Moksha but rather that they both reincarnated as human beings to follow, support and encourage their religion on until the Confluence Age where in a degraded form, the founders and followers of this relligion must come back to the BKWSU to re-learn spirituality.
