But one who moves among objects, perceiving the unavoidable ones with senses, hearing and the rest, freed from passion and aversion, since the natural activity of the senses is led by passion and aversion, and the seeker of liberation is the one freed of these two; with the senses brought into his own mastery; one of governed self, whose inner instrument is governable at will: such a one reaches calm, serenity, well-being. When there is calm, what comes of it? He says.

But one who, in the manner described, has set his mind on Me, the Lord of all, the auspicious resort of the mind, and who, with all his taint burned away, moves among objects with senses free of passion and aversion and obedient to himself, that is, lives setting the objects aside, being one of obedient mind attains serenity: he becomes one whose inner organ is pure.

This is a brief sub-gloss. For a fuller reading of this verse, see Madhusūdana, Śaṅkara, or Rāmānuja above.

Krishna states the fruit of the conquest of the senses with the next two verses. He whose self is governed, even while he experiences objects, is one of conquered self; that is the sense. 'Serenity' (prasada) means the serenity of the mind.
