Bhagavadgita 2.p5.5

2.p5.5

perform actions, casting off (all) attachment, and being equable in success or ill-success; (such) equability is called devotion. Action, O Dhanañgaya! is far inferior to the devotion of the mind. In that devotion seek shelter. Wretched are those whose motive (to action) is the fruit (of action). He who has obtained devotion in this world casts off both merit and sin. Therefore apply yourself to devotion; devotion in (all) actions is wisdom. The wise who have obtained devotion cast off the fruit of action; and released from the shackles of (repeated)births, repair to that seat where there is no unhappiness. When your mind shall have crossed beyond the taint of delusion, then will you become indifferent to all that you have heard or will heard. When your mind, confounded by what you have heard, will stand firm and steady in contemplation, then will you acquire devotion.
