The Brahman of the Hindus, like the Dharmakaya of the Buddhists, and the Tao of the Taoists, can be seen, perhaps, as the ultimate unified field, from which spring not only the phenomena studied in physics, but all other phenomena as well.
In the Eastern view, the reality underlying all phenomena is beyond all forms (e.g. beyond a god) and defies all description and specification. It is, therefore, often said to be formless, empty, or void. But this emptiness is not to be taken for mere nothingness. It is, on the contrary, the essence of all forms and the source of all life.
-Fritjof Capra, The Tao of Physics
