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.

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.
