There are four stages of understanding emptiness in tibet an buddhism. The first is the mind only school, which says there's no self and world outside has no existence. Then comes sothentrica mademaca - not only is that external world empty, but subject is also empty. And lastly chin matra: consciousness only; universe like a magical appearance or dream.
"I, the One, illumine this body and also reveal this universe. Therefore, mine is all this universe or indeed nothing is mine." Inspired by this verse from the Ashtavakra Gita, Swami Sarvapriyananda speaks on the nature of the Self.
