In the mind, whatever i am experiencing like seeing a table, not one bit of it is other than awareness. In awareness arises this wristy dismodification of the mind seeing table. Whatever is in consciousness must be pervaded through and through by consciousness. And its seeing in the mind, mind. It is mine internal. So now see the steps you have gone from a notion of an external, independen reality existing outside me.
Inspired by the 15th chapter of the Ashtavakra Gita, Swami Sarvapriyananda gives a discourse on the nature of the Self.
