Bhagavad Gita · Jnana Karma Sannyasa YogaChapter 4, Shloka 37 (4.37)

The simile of fire. However much wood there is, a fierce fire turns it to ash. So too, however large the store of actions.

Shankaracharya — "nirbīja" — seedless. Na hi sākṣād eva jñānāgniḥ karmāṇi indhanavat bhasmīkartuṃ śaknoti; tasmāt samyag-darśanaṃ sarva-karmaṇāṃ nirbījatve kāraṇam — knowledge cannot literally burn actions like wood; the meaning is that right vision makes all actions seedless (unable to bear fruit). And an important distinction: yena karmaṇā śarīram ārabdhaṃ tat pravṛtta-phalatvāt upabhogenaiva kṣīyate — the karma that began this body (prarabdha) has already started bearing fruit, so it is exhausted only by being experienced. Knowledge burns the remaining actions — those done before knowledge that are not yet bearing fruit, those done along with knowledge, and those of many past births.

Acharya Ramanuja: ātma-yāthātmya-jñāna-rūpaḥ agniḥ jīvātma-gatam anādi-kāla-pravṛttāneka-karma-sañcayaṃ bhasmīkaroti — the fire of true knowledge of the self burns to ashes the store of countless actions, running from beginningless time, that lies in the individual soul.
