dhūmena

धूमेनाव्रियते वह्निर्यथाऽऽदर्शो मलेन च

dhūmena — by smoke

As smoke covers fire, as dust covers a mirror, as the womb covers the embryo, so this covers knowledge.

धूमो रात्रिस्तथा कृष्णः षण्मासा दक्षिणायनम्

dhūmaḥ — smoke

Smoke, night, the dark fortnight, the six months of the southern course: departing then, one reaches the light of the moon and returns.

सहजं कर्म कौन्तेय सदोषमपि न त्यजेत्

dhūmena — with smoke

The work that comes with your own nature should not be abandoned even if it is flawed, son of Kunti. Every undertaking is wrapped in fault, as fire is wrapped in smoke.
