Bhagavad Gita Chapter 18 Verse 57
भगवद् गीता अध्याय 18 श्लोक 57

चेतसा सर्वकर्माणि मयि संन्यस्य मत्परः।
बुद्धियोगमुपाश्रित्य मच्चित्तः सततं भव।।18.57।।



English Translation - Swami Gambirananda
18.57 Mentally surrendering all actions to Me and accepting Me as the supreme, have your mind ever fixed on Me by resorting to the concentration of your intellect.


English Translation of Ramanuja's Sanskrit Commentary
18.57 By your mind means with thought which considers the self as belonging to Me and as controlled by Me. For, it has been declared:  Surrendering all your acts to Me with a mind focussed on the self (3.30). Surrendering all acts to Me along with agentship and the object of worship and regarding Me as the goal, i.e., constantly contemplating that I alone am to be attained as the goal; performing all acts; and resorting to Buddhi-Yoga  - focus your mind on Me always. Buddhi Yoga here implies the mental attitude special to the seeker of salvation in regard to agency of works, the fruits etc.
