Yin and Yang- Chinese origin Purusha and Prakriti- Indian Origin I will stick to Yin and Yang words, since they are widely known and better understood, even though both - Indian and Chinese words imply the same thing. These are the concepts to be UNDERSTOOD and DESCRIPTION Is often inadequate. However, still refer to wiki just to refresh our memory- "Yin and yang are actually complementary, not opposing, forces, interacting to form a whole greater than either separate part; in effect, a dynamic system. Everything has both yin and yang aspects, (for instance shadow cannot exist without light). Either of the two major aspects may manifest more strongly in a particular object, depending on the criterion of the observation" Now the main argument- Can I say- Matter and energy as described in modern physics is the same- Yin and Yang? Whatever way I tried against this argument- I could not reach to conclusion. Can someone prove to me that matter and energy are totally different terms and in no way we can equate them with Yin and Yang? Else, I am reaching to the conclusion that science has followed religion-at least here.
