The “Microvita Theory” has been founded by Shrii Prabhat Ranjan Sarkar. The study of Microvita comes under the discipline metaphysics. Microvita are living entities that come within the scope of physicopsychic expressions. Physically, they are smaller or subtler than atoms or electrons. In the mental realm they may be subtler than ectoplasm, which is the subtle substance that composes the objective portion of the mind. Microvita are not protoplasmic in nature. They are much subtler than carbon atoms which are presently considered to be the starting point of life in the universe.
