Bhagavad Gita Chapter 2, Verse 65

प्रसादे सर्वदुःखानां हानिरस्योपजायते । प्रसन्नचेतसो ह्याशु बुद्धिः पर्यवतिष्ठते ॥

prasāde sarva-duḥkhānāṁ hānir asyopajāyate | prasanna-cetaso hy āśu buddhiḥ paryavatiṣṭhate ||

In tranquility, the destruction of all sorrows arises. Indeed, for one with a serene mind, the intellect quickly becomes steady.

Krishna reveals what prasāda (tranquility from 2.64) actually does. 'Prasāde sarva-duḥkhānāṁ hāniḥ'—in that tranquility, all sorrows get destroyed. Not managed or suppressed—destroyed at their root. Why? Because most suffering comes from rāga-dveṣa patterns. When you're free from those, their effects dissolve. Then: 'Prasanna-cetaso āśu buddhiḥ paryavatiṣṭhate'—with serene mind, intellect quickly becomes steady. This is the upward spiral: let go of attachments/aversions → prasāda arises → sorrows end → clear thinking emerges.
