ei-mate vaiṣṇava saba nīlācale āilā
daive jagannāthera se dina jala-līlā
ei-mate—in this way; vaiṣṇava saba—all the Vaiṣṇavas; nīlācale āilā—came to Nīlācala; daive—by chance; jagannāthera—of Lord Jagannātha; se dina—that day; jala-līlā—pastimes in the water.
Thus all the Vaiṣṇavas from Bengal went to Jagannātha Purī. By chance, they arrived on the day when Lord Jagannātha performs pastimes in the water.
