TEXT 37
yathaidhāṁsi samiddho ’gnir
bhasma-sāt kurute ’rjuna
jñānāgniḥ sarva-karmāṇi
bhasma-sāt kurute tathā
yathā – just as; edhāṁsi – firewood; samiddhaḥ – blazing; agniḥ – fire; bhasma-sāt – ashes; kurute – turns; arjuna – O Arjuna; jñāna-agniḥ – the fire of knowledge; sarva-karmāṇi – all reactions to material activities; bhasma-sāt – to ashes; kurute – it turns; tathā – similarly.
As a blazing fire turns firewood to ashes, O Arjuna, so does the fire of knowledge burn to ashes all reactions to material activities.
Perfect knowledge of self and Superself and of their relationship is compared herein to fire. This fire not only burns up all reactions to impious activities, but also all reactions to pious activities, turning them to ashes. There are many stages of reaction: reaction in the making, reaction fructifying, reaction already achieved, and reaction a priori. But knowledge of the constitutional position of the living entity burns everything to ashes. When one is in complete knowledge, all reactions, both a priori and a posteriori, are consumed. In the Vedas (Bṛhad-āraṇyaka Upaniṣad 4.4.22) it is stated, ubhe uhaivaiṣa ete taraty amṛtaḥ sādhv-asādhūnī: “One overcomes both the pious and impious reactions of work.”
