Bhagavad Gita 2.61

तानि सर्वाणि संयम्य युक्त आसीत मत्परः।वशे हि यस्येन्द्रियाणि तस्य प्रज्ञा प्रतिष्ठिता ॥२.६१॥

tāni sarvāṇi saṃyamya yukta āsīta matparaḥvaśe hi yasyendriyāṇi tasya prajñā pratiṣṭhitā

Having restrained them all, he should sit steadfast, intent on Me; his wisdom is steady whose senses are under control.
