Even of a man who strives, who makes effort, O son of Kuntī, even of a discerning man, the senses, being of a churning nature, throw into turmoil, make distraught, a man who turns toward objects; and having made him distraught, they carry off by force, openly, even before his eyes, the mind, the mind joined with discerning awareness. Since it is so, therefore.

Without the beholding of the self, passion for the objects does not turn away; and while passion for the objects has not turned away, the senses, churning and strong, forcibly carry off the mind even of a discerning man who strives. So mastery of the senses depends on the beholding of the self, and the beholding of the self depends on mastery of the senses; and thus the standing in knowledge is hard to attain.

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

Even for a man of knowledge who lacks direct knowledge, even one who makes the ordinary effort, the senses carry off the mind. They do so for the person who identifies with the body. And what harm follows? They are 'churning' (pramathin), that is, of a nature to churn up the person.
