He whose thought is on no other, whose thought is not on any other object: the yogin who, with his thought on no other, constantly, at all times, remembers Me, the supreme Lord, perpetually. 'Constantly' states unbrokenness, 'perpetually' states length of time: not for six months or a year, but for as long as he lives, unbrokenly, he remembers Me. To that yogin I am easy to win, easily attained, O Pārtha, to the yogin ever yoked, whose mind is always composed. Since it is so, one should, with thought on no other, be always composed in Me. What comes of My being easy to win? Hear it told.

He who remembers Me ever, at all times, from the time of his rising and on, with a mind that goes to nothing else; who, by an exceedingly great love for Me, gaining no holding-up of himself without the remembrance of Me, makes a remembrance supremely dear to him; to that yogin, ever joined, longing for perpetual union, I am easy to gain, I myself am to be attained, not My state of being, lordship and the like. And I am easy to gain: unable to bear separation from him, I myself choose him; that is, I myself give the ripening of the worship that conforms to the attaining of Me, the dispelling of what obstructs it, and the exceedingly great love for Me and the rest. This is the meaning. For it is heard, 'whom this one chooses, by him He is gained', and it will be said, 'to them, ever joined, worshipping with love, I give that discipline of understanding by which they come to Me; out of compassion for them alone, I, abiding in their self, destroy the darkness born of ignorance with the shining lamp of knowledge'. From here on, in the rest of the chapter, the Lord states the no-return of the man of knowledge and the seeker of aloneness, and the return of the seeker of lordship.

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

'Of one ever joined' means of one who ever possesses the means; 'of the yogin' means of one whose yoga is complete.
