Śaṅkarācārya's commentary

"Mere": free from egotism, resolute in the faith that 'I act only for the sake of the Lord, not for my benefit.' 'Mere' should be construed along with 'body,' etc., with each one of them separately. Yogins are those who are devoted to works, free from egotism in all their acts, without attachment for their results. They act only for the purification of the mind (sattva). Wherefore, as thy duty lies only there, do thou only perform action.
