हिंदी अनुवाद - स्वामी रामसुख दास जी ( भगवद् गीता 2.65)
।।2.64  2.65।।वशीभूत अन्तःकरणवाला कर्मयोगी साधक रागद्वेषसे रहित अपने वशमें की हुई इन्द्रियोंके द्वारा विषयोंका सेवन करता हुआ अन्तःकरणकी प्रसन्नताको प्राप्त हो जाता है। प्रसन्नता प्राप्त होनेपर साधकके सम्पूर्ण दुःखोंका नाश हो जाता है और ऐसे प्रसन्नचित्तवाले साधककी बुद्धि निःसन्देह बहुत जल्दी परमात्मामें स्थिर हो जाती है।


English Translation of Sanskrit Commentary By Sri Shankaracharya's
2.65 Prasade, when there is serenity; upajayate, there follows; hanih, eradication; asya sarva-duhkhanam, of all his, the sannyasins, sorrow on the physical and other planes. Moreover, (this is so) hi, because; buddhih, the wisdom; prasanna-cetasah, of one who has a serene mind, of one whose mind is poised in the Self; asu, soon; pari-avatisthate, becomes firmly established; remains steady (avatisthate) totally (pari), like the sky, i.e. it becomes unmoving in its very nature as the Self.
The meaning of the sentence is this: Since a person with such a poised mind and well-established wisdom attains fulfilment, therefore a man of concentration [A man who is free whom slavery to objects of the senses.] ought to deal with the indispensable and scripturally non-forbidden objects through his senses that are free from love and hatred.
That same serenity is being eulogized:

2.65 See Comment under 2.68


English Translation of Ramanuja's Sanskrit Commentary
2.65 When the mind of this person gets serene, he gets rid of all sorrows originating from contact with matter. For, in respect of the peson whose mind is serene, i.e., is free from the evil which is antagonistic to the vision of the self, the Buddhi, having the pure self for its object, becomes established immediately. Thus, when the mind is serene, the loss of all sorrow surely arises.
