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

tāni sarvāṇi saṃyamya yukta āsīta matparaḥ
vaśe hi yasyendriyāṇi tasya prajñā pratiṣṭhitā

Meaning

Controlling all of them, one should sit in yoga with the mind fixed on me. One whose senses are under control has steady wisdom.
