While the actions are being entirely done by the modes of Nature, he whose self is bewildered by egoism thinks that it is his “I” which is doing them.
Gītā 3·27Prakriti is the Nature, mechanical, reflecting all her works in the conscious witness, the Purusha. Prakriti works by the inequality of her three modes, gunas, in perpetual collision and intermixture and mutation with each other ; and by her function of ego-mind she gets the Purusha to identify himself with all this working and so creates the sense of active, mutable, temporal personality in the silent eternity of the Self.
