“Brother-in-law! You say that to fight is sin. You are badly mistaken! It is refusing to fight, failing to put an end to the sinners, and so bringing harm upon the host of the supremely virtuous, that is sin; by the very act of not fighting you would be committing a great sin. If at this time you abandon your svadharma, you will fall to the lowest state. If you carry out your svadharma, no sin will touch you. Keep an even citta amid the pairs of opposites, and face them in battle with a firm citta.” For this very reason he taught eight ślokas in this chapter, beginning with the thirty-first śloka. In the thirty-seventh śloka he spoke of steadfastness in svadharma, and said that one must take part in karma with an even mind in pleasure and pain. The thirty-ninth śloka is a linking śloka. In it the Paramātma declared: “This has been taught to you in Sāṅkhya”; that is, “I have taught you Sāṅkhya Buddhi. Now I will make known Yoga Buddhi; listen.”
