What is the idea here? Everything belongs to īśvara, as consciousness with qualities (saguṇa brahma). As long as I think I possess anything, I am not free, because my well-being depends on that possession.

My car, my child, my career, my house, my achievements, my talents, my ego. It is a qualification for freedom to relinquish all of this. Not legally, but mentally. You should try it sometime. Mokṣa is inner freedom from dependence on objects. There is nothing more beautiful.

That is also the spirit of karma yoga. I surrender by returning my status as an individual to īśvara. Then I become free as consciousness. Because mamakāra is an identical twin with ego, ahaṅkāra, the dissolution of ego is paralleled by the dissolution of the sense of mine (also known as mamatva, mineness).

Mamakara is also known as mamatvam, “my-ness.”
