Bhagavad Gita · 7.17

तेषां ज्ञानी नित्ययुक्त एकभक्तिर्विशिष्यते।प्रियो हि ज्ञानिनोऽत्यर्थमहं स च मम प्रियः॥

teṣhāṁ jñānī nitya-yukta eka-bhaktir viśhiṣhyate priyo hi jñānino 'tyartham ahaṁ sa cha mama priyaḥ

Of these, the wise one, ever united with Me in single-minded devotion, is the best. For I am exceedingly dear to the wise, and they are dear to Me.
