D.: What is svarupa (form) and arupa [?] (formless) of the mind?M.: When you wake up from sleep a light appears, that is the light of the Self passing through Mahat tattva. It is called cosmic consciousness. That is arupa. The light falls on the ego and is reflected therefrom. Then the body and the world are seen. This mind is svarupa. The objects appear in the light of this reflected consciousness. This light is called jyoti.
