Siman 178

(12.) In that summer he sent me to Rabbi Yehoshua of blessed memory of the holy congregation of Dzerin — close to his passing — with a note [kvitl], that he should take in mind the names recorded there so that it would be good for him in the World to Come. And he said that through this Rabbi Yehoshua would be able to come to him immediately after his passing. And so it was — Rabbi Yehoshua came to him immediately upon his passing.
