The Yoga of Knowledge

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.
