Śaṅkarācārya's commentary

Sacrifice: the act of sacrifice. "Spoken of": by the learned. "These": sacrifice, gift and austerity. Or, 'tad-arthīyaṃ karma' may be interpreted to mean action for the sake of the Lord whose triple designation is the subject of treatment here. These acts of sacrifice, gift and austerity — even such of them as are not of the Sāttvic class and are imperfect — turn out to be Sāttvic and perfect ones, on applying to them with faith the triple designation of Brahman.
