2.68

तस्माद्यस्य महाबाहो निगृहीतानि सर्वशः | इन्द्रियाणीन्द्रियार्थेभ्यस्तस्य प्रज्ञा प्रतिष्ठिता ||२-६८||

tasmādyasya mahābāho nigṛhītāni sarvaśaḥ . indriyāṇīndriyārthebhyastasya prajñā pratiṣṭhitā ||2-68||

tasmāt
therefore
yasya
whose
mahā-bāho
O mighty-armed one
nigṛhītāni
so curbed down
sarvaśaḥ
all around
indriyāṇi
the senses
indriya-arthebhyaḥ
from sense objects
tasya
his
prajñā
intelligence
pratiṣṭhitā
fixed

Therefore, O mighty-armed, one whose senses are restrained from their objects is certainly of steady intelligence.
