Bhagavad Gita, Chapter 18, Verse 48

सहजं कर्म कौन्तेय सदोषमपि न त्यजेत् । सर्वारम्भा हि दोषेण धूमेनाग्निरिवावृताः

sahajaṃ karma kaunteya sadoṣamapi na tyajet | sarvārambhā hi doṣeṇa dhūmenāgnirivāvṛtāḥ

Translation

The duty born with oneself, O son of Kuntī, though faulty, one ought not to abandon; for, all undertakings are surrounded with evil, as fire with smoke.

— Alladi Mahadeva Sastri

Śaṅkarācārya's commentary

Born with oneself: born with the very birth of man. Faulty: as everything is composed of the three guṇas. All undertakings: whatever the duties are; both one's own as well as another's duties; for the reason here assigned is that they are all made up of the three guṇas. Though a man may perform another's duty, abandoning what is called his own duty, the duty born with himself, he is not free from fault; and another's duty brings on fear. Since it is not possible for any man who does not know the Self to give up action entirely, therefore he ought not to abandon action (karma).
