Bhagavad Gita Chapter 2.65
prasāde sarva-duḥkhānāḿ
hānir asyopajāyate
prasanna-cetaso hy āśu
buddhiḥ paryavatiṣṭhate
Translation
For one thus satisfied [in Krishna consciousness], the threefold miseries of material existence exist no longer; in such satisfied consciousness, one’s intelligence is soon well established.
