Bhagavad Gita, Chapter 18, Verse 66

Relinquishing all Dharmas take refuge in Me alone; I will liberate you from all sins; grieve not.

Let go of every other duty and surrender, Krishna says. The promise is freedom, and no more grief.

Krishna doesn't soften this final ask. Abandoning all dharmas is stated plainly, backed by a direct promise of liberation, and fear itself is addressed head-on, not left unspoken.
