Translation:
O most eminent of brāhmaṇas, you are all indeed extremely fortunate, since you have already placed within your hearts Lord Śrī Nārāyaṇa — the Personality of Godhead, the supreme controller and the ultimate Soul of all existence — beyond whom there is no other god. You have undeviating love for Him, and thus I request you to worship Him.
