It is as real as human beings, or matter. Yes, says Vedanta . This, probably, is one of the ways of understanding matter, as referring to the constituent substance of the layers of the human personality. The body is a material substance, but constituted of layers of matter, and not one solid thing. Though, when man consciously thinks, he cannot think of himself to be anything other than the physical body, mostly he is psychological in nature.
Human life is more mental than physical.
Actually, it is the essence of one s personality. But this classification is not different from what is given above. The Gross Body, known as sthula-sarira in Sanskrit, is nothing but the physical body. This is the outermost layer. This mass of flesh, bone, marrow, and the solidity that is seen, is the physical body.
