Śaṅkarācārya's commentary

Some Yogins, devotees to action, perform only sacrificial rites in devotion to the Gods, while others who know Brahman, the Absolute, sacrifice the Self by the Self in the fire of Brahman. The oblation (āhuti) in this latter sacrifice is yajña, the Self, who is in reality one with Brahman but who is conditioned by the upādhis (such as buddhi) with all their attributes superimposed upon Him. This oblation of the Self is poured by the Self into Brahman — here termed fire, the place into which that oblation is poured. To know the conditioned Self as identical with the unconditioned Brahman is to sacrifice the Self in Brahman.
