Srimad Bhagavatam 6.1.15

6.1.15

केचित्केवलया भक्त्या वासुदेवपरायणा: । अघं धुन्वन्ति कार्त्स्‍न्येन नीहारमिव भास्कर: ॥ १५ ॥

kecit kevalaya bhaktya vasudeva-parayanah agham dhunvanti kartsnyena niharam iva bhaskarah

kecit
some people
kevalaya bhaktya
by executing unalloyed devotional service
vasudeva
to Lord Krsna, the all-pervading Supreme Personality of Godhead
parayanah
completely attached (only to such service, without dependence on austerity, penance, cultivation of knowledge or pious activities)
agham
all kinds of sinful reactions
dhunvanti
destroy
kartsnyena
completely (with no possibility that sinful desires will revive)
niharam
fog
iva
like
bhaskarah
the sun

Only a rare person who has adopted complete, unalloyed devotional service to Krsna can uproot the weeds of sinful actions with no possibility that they will revive. He can do this simply by discharging devotional service, just as the sun can immediately dissipate fog by its rays.
