Bhagavad Gita, Chapter 18, Verse 54

Brahman-become, tranquil-minded, he neither grieves nor desires; the same to all beings, he attains to supreme devotion unto Me.

Real knowledge here is shown leading somewhere further, straight into devotion, not stopping at itself.

Krishna names this realization's natural endpoint directly, supreme devotion, closing the gap some might assume exists between knowledge and love. Real understanding, taken far enough, arrives at devotion anyway.
