Bg 2.65

prasāde sarva-duḥkhānāṁ
hānir asyopajāyate
prasanna-cetaso hy āśu
buddhiḥ paryavatiṣṭhate
Word for word: 
prasāde — on achievement of the causeless mercy of the Lord; sarva — of all; duḥkhānām — material miseries; hāniḥ — destruction; asya — his; upajāyate — takes place; prasanna-cetasaḥ — of the happy-minded; hi — certainly; āśu — very soon; buddhiḥ — intelligence; pari — sufficiently; avatiṣṭhate — becomes established.
Translation: 
For one thus satisfied [in Kṛṣṇa consciousness], the threefold miseries of material existence exist no longer; in such satisfied consciousness, one’s intelligence is soon well established.
