Śaṅkarācārya's commentary

When you go into battle treating alike pleasure and pain, gain and loss, victory and defeat, you incur no sin. The sin attaches not to the act but to the attachment that prompts it. With this verse the Lord turns from the Sāṅkhya teaching (concerning the eternal Self) to the Yoga teaching — the path of right action without attachment — which is unfolded in what follows.
