Brahman, Tao, Sunyata, Thales, Einstein
Are Brahman, Tao and Sunyata (Buddhist word for emptiness) all different interpretations of what is essentially the same thing? They seem to indicate some kind of uniform essence within all existing phenomena, whether that essence is something or nothingness, and the goals of the three respective religions appear to be the bringing about of a state of cohesion between the individual and this all-pervasive absolute principle or reality or thing.
Here are some short definitions courtesy of wikipedia:
"The sages of the Upanishads teach that Brahman is the ultimate essence of material phenomena (including the original identity of the human self) that cannot be seen or heard but whose nature can be known through the development of self-knowledge (atma jnana).[7] According to Advaita, a liberated human being (jivanmukta) has realised Brahman as his or her own true self."
"Dao can be roughly thought of as the flow of the universe, or as some essence or pattern behind the natural world that keeps the universe balanced and ordered.[7] It is related to the idea of qi, the essential energy of action and existence. Dao is a non-dual concept – it is the greater whole from which all the individual elements of the universe derive. Keller considers it similar to the negative theology of Western scholars,[8] but Dao is rarely an object of direct worship, being treated more like the Hindu concepts of karma or dharma than as a divine object.[9] Dao is more commonly expressed in the relationship between wu (void or emptiness, in the sense of wuji) and yinyang (the natural dynamic balance between opposites), leading to its central principle of wu wei (non-action, or action without force)."
"Śūnyatā, (Sanskrit, also shunyata; Pali: suññatā), in Buddhism, translated into English as emptiness, voidness[1], openness[2], spaciousness, thusness, is a Buddhist concept which has multiple meanings depending on its doctrinal context. In Mahayana Buddhism, it often refers to the absence of inherent essence in all phenomena."
What do you think? I know Western religions are more popular than Eastern ones in this sub-forum, but I'd appreciate any thoughts you might have. It might be that I'm entirely wrong in my assessment and that these ideas are in opposition rather than essential agreement.
I also sometimes wonder whether these Eastern concepts have any relationship to the pre-socratic philosopher Thales' famous and what I take to be metaphorical assertion that "everything is water," as well as Einstein's equation E = MC^2, from which I've been told we can infer the fact that everything in the universe is in fact a form of energy. Plato's forms may also have a link to all of this, but I'm pretty sure it is of a far more tenuous and disparate nature than that of the others.
Thanks for reading and for any replies!
