3.29.10

karma-nirhāram uddiśya parasmin vā tad-arpaṇam /
yajed yaṣṭavyam iti vā pṛthag-bhāvaḥ sa sāttvikaḥ //

6. He who is desirous of getting rid of all his Karma or of offering his actions in worship to the Supreme Lord or with the idea that it is his duty, worships Me with the notion of difference—he is of the Satvika Class.
