Shankaracharya's commentary, trans. Alladi Mahadeva Sastry (1897)
[1]The duty born with oneself, O son of Kunti, though faulty, one ought not to abandon; for, all undertakings are surrounded with evil, as fire with smoke.

सहजं कर्म कौन्तेय सदोषम् अपि न त्यजेत् । सर्वारम्भा हि दोषेण धूमेनाग्निर् इवावृताः ॥
saha-jaṃ karma kaunteya sa-doṣam api na tyajet | sarvārambhā hi doṣeṇa dhūmenāgnir ivāvṛtāḥ ||
"Do not abandon one's innate duty even if imperfect — all undertakings are enveloped by fault as fire by smoke."
