This is a brief sub-gloss. For a fuller reading of this verse, see Madhusūdana, Śaṅkara, or Rāmānuja above.
Acts of sacrifice, giving, and austerity, this threefold action, are not to be given up; they are to be done. Why? Because sacrifice, giving, and austerity are purifying; they bring about inner purity for thoughtful people who do not crave the fruit.
