Abstract: Classical physics was based on the principle of Newtonian Relativity which is basically about the relativity of motion, idea of absolute space and absolute time. In twentieth century, it was the principle of Einsteinean Relativity that shattered the major concepts of classical physics. It is the relativity of space and time here and now space-time is regarded as one integral whole. Einstein made it clear that space and time are not separable entities but single continuum. From the relativity of space and time, another important conclusion has been derived by Einsteinthat is the relativity of mass and ultimately the inter changeability of mass and energy. Thus the whole journey of physics from classical physics to modern physics seems like an echo of Buddhist and Vedantic concepts proceeding towards the ultimate unification of concepts. In Buddhism, Vedanta and Neo-Vedanta the relativity of space and time that form the physical world has already been established. Through this relativity, the highest point– the ultimate state of consciousness is reached where remains no distinction between mind and body, subject and object, where there is no space without time, no time without space, they are interpenetrating.
