Taraka Brahma is considered what is perfect knowledge (Brahma) with excellent splendour and save from womb, birth, old age, death and murder like sins. Assuming the living-organisms and God both covered by the illusion (Maya) who abandons all others by saying "it is unlimited" (Neti-Neti), can attain the residual i.e. "one or unique Brahma". (The residual after abandoning material ties is the true and purified knowledge).
