Update from Tsunami-Foreseeing Rabbi
Daniel has updated us again in the Hebrew forum about what the Rav mentioned in the starting post said last Shabbat.
He said that the Rav had told them that from Shamayim (שמים, heavens) they revealed to him that the only reason the Geula (גאולה, redemption) is not arriving yet is the lack of unity within the people of Israel. Furthermore, they asked him from Shamayim to talk about the subject of unity in Israel, and he asked for everyone to talk about it.
Daniel wrote that he was afraid to write such things as a Rav talking with Shamayim in this generation, because people might not believe it, because almost no one talks this way in our generation. However, to emphasize who this Rav was and still not identify him by name, he added to what he said before that the Rav "himself learned from a renowned tzadik זצוק"ל known for his wonder making and his future sight", that the renowned Tzadik that was the teacher of the Rav was the renowned Rav Nachmani, known for his accurate future sight.
