From the diary of a Tomim, written on the day after Pesach, 5710/1950:

?????? Today, after davening in the room of the late Rebbe [Rayatz], the Ramash [the Rebbe] spoke to several people. He said, ???Why didn???t a larger crowd come yesterday? When all the doors were locked, a huge crowd would gather and everyone would be squashed. Yet now, when all the doors are open, no one comes! ??? As Eliyahu Hanavi cannot be everywhere at the same time, sparks of his being are found in every place. Yet in the case of Rav Hamnuna Saba, Eliyahu Hanavi would appear in his entirety. Therefore, here, where the Rebbe runs ten Sedarim, could there be a greater revelation than that!???????
