Ch 18, Sh 66 continued 6, Bhagawad Gita, Shankar Bhashya

Objection: May it not be argued that it cannot be proved that all actions are due to ignorance?
Reply: No, (it can be proved,) as in the case of slaying a Brahmin. Although the nityakarmas are known from the scriptures, still they are meant only for the ignorant. As such an action as killing a Brahmin, even though known to be a source of evil from the scripture prohibiting it, is still perpetrated by one who has defects such as ignorance, passion, etc. because impulsion to any action is otherwise not possible, so also is it with regard to the nitya, naimittika and kamya actions.
Objection: May it not be held that impulsion to nityakarma etc. is not possible if the Self be not known as a distinct entity? [Unless one knows the Self to be distinct from the body etc. he will not perform the nityakarmas etc. meant for results in the other worlds, viz heaven etc.
Reply: No, since it is seen that with regard to actions which are of the nature of motion and are accomplished by the not-Self, one engages in them with the idea, 'I do.' [The actionless Self is not the agent of the movements of the body etc. Still agent ship is superimposed on it through ignorance.]
Objection: Can it not be said that the notion of egoism with regard to the aggregate of body etc. occurs in a figurative sense; it is not false?
