Bhagavad Gita 4.19

yasya sarve samārambhāḥ

kāma-saṅkalpa-varjitāḥ

jñānāgni-dagdha-karmāṇaṁ

tam āhuḥ paṇḍitaṁ budhāḥ

One is understood to be in full knowledge whose every endeavor is devoid of desire for sense gratification. He is said by sages to be a worker for whom the reactions of work have been burned up by the fire of perfect knowledge.
