इन्द्रियाणां हि चरतां यन्मनोऽनुविधीयते।
तदस्य हरति प्रज्ञां वायुर्नावमिवाम्भसि।।2.67।।
2.67 For the mind, which follows in the wake of the wandering senses, carries away his discrimination, as the wind (carries away) a boat on the waters.
2.67 Hi, for; yat manah, the mind which; anu-vidhiyate, follows in the wake of; caratam, the wandering; indriyani, senses that are tending towards their respective objects; tat, that, the mind engaged in thinking [Perceiving objects like sound etc. in their respective varieties.] of the objects of the senses; harati, carries away, destroys; asya, his, the sannyasins; prajnam, wisdom born from the discrimination between the Self and the not-Self. How? Iva, like; vayuh, the wind; diverting a navam, boat; ambhasi, on the waters. As wind, by diverting a boat on the waters from its intended course, drives it along a wrong course, similarly the mind, by diverting the wisdom from the pursuit of the Self, makes it engage in objects. After having stated variously the reasons for the idea conveyed through the verse, For, O son of Kunti, etc. (60), and having established that very idea, the Lord concludes thus:
Indriyaanaam hi charataam yanmano’nuvidheeyate; Tadasya harati prajnaam vaayur naavam ivaambhasi.
indriyāṇām—of the senses; hi—indeed; charatām—roaming; yat—which; manaḥ—the mind; anuvidhīyate—becomes constantly engaged; tat—that; asya—of that; harati—carries away; prajñām—intellect; vāyuḥ—wind; nāvam—boat; iva—as; ambhasi—on the water
