Kṛṣṇa concludes this section on the various types of yoga. He mentions those who practice sacrifice through ‘niyatāhārāḥ’—regulated eating or fasting. By controlling the most basic instinct of hunger, they gain mastery over their other senses and offer their very vitality to the Divine. He declares that all these diverse practitioners are ‘yajña-vido’, or knowers of sacrifice. Despite their different methods, they all achieve the same result: they become ‘yajña-kṣapita-kalmaṣāḥ’, cleansed of their past sinful reactions. The act of sacrifice acts like a spiritual detergent that washes the soul. This is a beautiful and inclusive message. Whether you are a scholar, a philanthropist, a meditator, or someone who simply practices self-restraint, your effort is recognized. Kṛṣṇa is telling Arjuna that the specific form of the work is less important than the spirit of sacrifice behind it. Any honest effort to move beyond one’s ego is a valid path to purification.
