Bhagavad Gita 2.65

प्रसादे सर्वदुःखानां हानिरस्योपजायते।प्रसन्नचेतसो ह्याशु बुद्धिः पर्यवतिष्ठते॥

prasāde sarvaduḥkhānāṃ hānirasyopajāyate |prasannacetaso hyāśu buddhiḥ paryavatiṣṭhate ||

In that peace, all pains are destroyed; for the intellect of the tranquil-minded soon becomes steady.

Having attained peace, he becomes free from misery; for when the mind gains peace, right discrimination follows.

Our plain-language meaning of this verse is waiting for scholar review.
