Bhagavatapurana 1.5.12

1.5.12

naiṣkarmyam apyacyutabhāvavarjitaṃ na śobhate jñānam alaṃ nirañjanam /
kutaḥ punaḥ śaśvadabhadram īśvare na cārpitaṃ karma yadapyakāraṇam //

12. Though one (identical) with the essence of Brahman, the destroyer of besetting conditions, that knowledge does not shine well (cannot be of great value and efficacy), which is destitute of devotion to Achyuta. How then could that karma be good, which never tends to eternal welfare, whether prompted by desires or not, so long as it is not offered to the Lord.
