teṣāṁ jñānī nityayukta ekabhaktirviśiṣyate। priyo hi jñānino'tyarthamahaṁ sa ca mama priyaḥ ॥17॥

All these are indeed noble, but among them, the Wise One (jñānī), who is ever steadfast and has single-pointed devotion, excels. Such a wise person is considered by Me as My very essence. I am exceedingly dear to him, and he is also dear to Me. Such a wise one is steadfastly situated in Me, is firmly established, and attains Me alone as the supreme and unsurpassed goal.
