18.17 He who, through the contemplation of the agency of the Supreme Being, is free from the self-conceit, 'I alone do everything'; he whose understanding is not therefore tainted, and has come to be informed by the understanding; 'As I am not the agent of this work, its fruit is not connected with me; so this work does not belong to me' - such a person, though he slays all these men, not merely Bhisma, etc., does not slay them. Therefore, he is not bound by the actions known as battle. The meaning is that the fruits of such actions do not accrue to him.

Sri Krsna now teaches how action is induced. For this he differentiates actions generated by Sattva and the other Gunas. The object is to inculcate the desirability of the Sattvika type. For, only meditation on the self not being the agent, brings about the growth of Sattva.
