Others who regulate their diet offer life-breaths in life-breaths. All these are knowers of sacrifice, whose sins are destroyed by sacrifice.

Others, regulating their food, offer the life breaths into the life breaths. All of these know sacrifice, and through sacrifice their impurities are destroyed.

The list ends with those who regulate their eating and offer the life breaths into the life breaths, which many take to mean that through fasting and moderation the vital forces are drawn inward and refined. Krishna then sums up: all these people truly know sacrifice (yajña), and by it their impurities, kalmaṣa, are burned away. The conclusion matters more than any single item. Many different disciplines are valid, and what makes them sacrifice is the spirit of offering that purifies the one who practises.
