This verse contains one of the Gītā's most vivid and memorable similes: the mind following the senses is like a ship at the mercy of the wind on open water. The image is visceral — the sailor loses all control, spinning wherever the gusts blow, completely unable to navigate toward a chosen destination. 'Caratām indriyāṇām' describes senses that are roaming freely, without direction or restraint. When the mind ('manaḥ') follows these roaming senses — 'anuvidhīyate' means literally 'follows along behind' — it is no longer the master but the servant. And when the mind is the servant of the senses, prajñā (wisdom, spiritual discernment) is 'harati' — carried away, stolen, lost. The nautical metaphor was especially meaningful in Krishna's era, when ships on the Arabian Sea were entirely dependent on wind. A ship without a helmsman who could read and counter the wind would be blown off course, wrecked on rocks, or lost at sea. So too the person whose mind passively follows every sensory impulse. The remedy is implied: be the helmsman, not the ship. Direct your attention; do not let your senses direct it for you.
