Krishna introduces the supreme operating principle of the universe: Yajña (Sacrifice/Offering). He states an absolute law: If action is performed for any reason other than as a sacrifice (yajñārthāt karmaṇo 'nyatra), that action will bind the soul to the material world (loko 'yaṃ karma-bandhanaḥ). Therefore, he commands Arjuna to perform his actions entirely for the sake of that sacrifice (tad-arthaṃ karma), completely freed from personal attachment (mukta-saṅgaḥ samācara).
