B.G 3.34

इंद्रियस्येंद्रियस्यार्थे रागद्वेषौ व्यवस्थितौ। तयोर्न वशमागच्छेत् तौ ह्यस्य परिपन्थिनौ ॥३४॥

iṁdriyasyēṁdriyasyārthē rāgadvēṣau vyavasthitau। tayōrna vaśamāgacchēt tau hyasya paripanthinau ॥34॥

[इंद्रियस्य इंद्रियस्य अर्थे राग द्वेषौ व्यवस्थितौ। तयोः न वशम् आगच्छेत् तौ हि अस्य परिपन्थिनौ॥
iṁdriyasya = from the Indriyas; iṁdriyasya = from the Indriyas; arthē = the objects; rāga = attachment; dvēṣau = aversion; vyavasthitau = are established;। tayōḥ = in them; na = not; vaśam = under their sway; āgacchēt = should come; tau = those two; hi = indeed; asya = of these; paripanthinau = obstacles;॥]

By senses dwelling on sense objects, attachement and aversion necessarily arise. Let not one come under the sway of these two. Indeed, they are obstacles.
