सहजं कर्म कौन्तेय सदोषमपि न त्यजेत्।
सर्वारम्भा हि दोषेण धूमेनाग्निरिवावृताः।।१८.४८।।

Meaning

The duty that falls to one's lot of its own accord should not be abandoned, though it may have its defects. All acts are marred by defects, just as fire is obscured by smoke.

Hindi Meaning

हे कुन्तीनन्दन ! दोषयुक्त होनेपर भी सहज कर्मका त्याग नहीं करना चाहिये; क्योंकि सम्पूर्ण कर्म धुएँसे अग्निकी तरह किसी-न-किसी दोषसे युक्त हैं।
