Bhagavad Gita, Chapter 18, Verse 68

He who with supreme devotion to Me will teach this deeply profound philosophy to My devotees, shall doubtless come to Me alone.

Teaching this knowledge to others is named here as an even greater act than simply practicing it alone.

Krishna elevates the real act of sharing this teaching above private devotion itself. Real generosity in passing this on is treated as its own, especially significant form of love.
