2.65

Sanskrit

प्रसादे सर्वदुःखानां हानिरस्योपजायते । प्रसन्नचेतसो ह्याशु बुद्धिः पर्यवतिष्ठते ॥

prasāde sarvaduḥkhānāṃ hānir asyopajāyate prasannacetaso hy āśu buddhiḥ paryavatiṣṭhate

Translation

In that Peace the extinction of all pains ariseth for him, for of him whose heart is peaceful the Reason soon attaineth equilibrium.

Annie Besant · The Bhagavad-Gita, translated by Annie Besant (4th ed., 1922) — Wikisource · Public Domain

Explanation

Picks up directly from verse 64’s “goeth to peace”: that peace isn’t a passive relief but has its own consequence — all pains dissolve, and buddhi settles into equilibrium quickly, almost as a side effect. This causal ordering (peace first, clarity of mind following) matters, and verse 66 immediately states the same relationship in reverse, as a warning.
