Kṛṣṇa explains the total dissolution of karma for a person in knowledge. When a person is ‘gata-saṅgasya’ (unattached) and ‘muktasya’ (liberated), and their mind is constantly fixed in spiritual truth, their entire life becomes an act of sacrifice, or ‘Yajña’. For such a person, all the results of their work ‘samagraṁ pravilīyate’—they merge or dissolve completely into the Absolute. There is no ‘karmic debt’ left over. It is like writing on water; as soon as the action is done, the trace disappears. No residue of ego remains to pull the soul back into another material birth. Kṛṣṇa is showing Arjuna that the only way to truly finish with the material world is to dedicate every act to the Supreme. This turns ‘work’ into ‘worship’. If Arjuna fights for the sake of this sacrifice, his arrows will leave no stain on his soul, and his participation in the war will become his path to the infinite.
