Bhagavad Gita 4.37

यथैधांसि समिद्धोऽग्निर्भस्मसात्कुरुतेऽर्जुन।ज्ञानाग्निः सर्वकर्माणि भस्मसात्कुरुते तथा॥

yathaidhāṃsi samiddho'gnirbhasmasātkurute'rjuna |jñānāgniḥ sarvakarmāṇi bhasmasātkurute tathā ||

As the blazing fire reduces fuel to ashes, O Arjuna, so does the fire of knowledge reduce all actions to ash.

As the kindled fire consumes the fuel, so, O Arjuna, the embers of action are burnt to ashes in the flame of wisdom.

Our plain-language meaning of this verse is waiting for scholar review.
