Vedānta distinguishes three bodies. The gross body is the physical body experienced in waking. The subtle body, made of the vital breaths, the senses, mind and intellect, is the vehicle of dreams and passes from life to life. The causal body is beginningless ignorance itself, experienced in deep sleep. The self is the witness of all three.
