' Richo Akshare Parame Vyoman ' says the Rig Veda, that Knowledge is basically structured in Consciousness.
The Rishies could write the wonderful Vedas, because their Consciousness levels were high. The Vedas were never written, they were cognised in higher states of Consciousness !
They saw the Self, in the Self, by the Self, because everything was their own Self.
Our aim is to improve our levels of Consciousness and achieve Unity Consciousness, which is the summum bonum of Life.
