Bhagavad-gītā As It Is · Text 18.48
Natural duties and perfection through work
सहजं कर्म कौन्तेय सदोषमपि न त्यजेत् ।
सर्वारम्भा हि दोषेण धूमेनाग्निरिवावृता: ॥ ४८ ॥
saha-jaṁ karma kaunteya
sa-doṣam api na tyajet
sarvārambhā hi doṣeṇa
dhūmenāgnir ivāvṛtāḥ
Translation
Every endeavor is covered by some fault, just as fire is covered by smoke. Therefore one should not give up the work born of his nature, O son of Kuntī, even if such work is full of fault.
