I've studied the philosophies of Buddhism and Hinduism as well as modern physicists examining consciousness for over 30 years, they all seem to basically align, spacetime exists but isn't fundamental, consciousness is the basis, the absolute, although the 14th century German Christian mystic postulated that beyond consciousness was the void of nothing. Buddha was right I think when he said there is no self, no doer of action and the world is empty because nothing exists in and of itself, everything relies on everything else for their temporary brief manifestations which manifest within the field of consciousness. As the Indian sage Nisargadatta said, "You are not the body nor are you the mind, there is nobody", it is a mistake to think of yourself as a person but rather the true self is a localization of the absolute which, as the NASA physicist Tom Campbell (my big T.O.E) wrote, is itself evolving, we, as avatars, exist in the data stream of consciousness to lower its entropy, this is similar but more extreme than the cognitive scientist Donald Hoffman ('The end of Spacetime') who as an emirate at an American university is producing mathematics and computer simulations with his international team to show that everything is made up of agents of consciousness and the reality that we perceive is only 'eye candy'. All seem to converge to one basic idea, only consciousness is real. Again, Nisargadatta said, "That which is real does not change, that which changes is not real". Through deep introspective meditation one can come to the conclusion, inside you are emptiness, nothing, outside you are everything. The direct path to awakening was proscribed by the revered 20th century Indian sage Ramana Maharshi as to simply meditate on 'who am I', the question won't result in an answer but is designed to dissolve the questioner.
