Jñāneśvarī (commentary on the Bhagavadgītā) 4.131

4.131

sarvāṇīndriyakarmāṇi prāṇakarmāṇi cāpare
ātmasaṃyamayogāgnau juhvati jñānadīpite
ekīṃ yayāparī pārthā |
doṣu kṣāḷile sarvathā |
āṇikīṃ hṛdayāraṇīṃ maṃthā |
viveku kelā ||

In this manner, O Pārtha, some / washed away fault entirely; / others made discernment their churning-stick / upon the fire-drill of the heart.
