CA- thanks!
the Zohar (Midrash Ne’elam – Toldot 140a), and the “Leshem Shevo v’Achlamah”(Drushei Olam HaTohu, 2:4:12:9-12)
Moshiach can come any day we are zoche as Eliyahu Hanavi told Rabbi Yehoshua Ben Levi he’ll come- hayom (Im tishma bkolo). These are dates that if it didn’t happen before, are auspicious based on their timing or where the world will be at etc. To me what’s special about the Zohar , is that it lists other times that have come true, such as “the opening of the waters (wisdoms) of below and above” that happened at the time of the revelation of Chassidus/ the industrial revolution, if you know what I’m referring to (happy to elaborate if not)
Also does the whole 6000 thing come from the Zohar as well or is it gemara? Regardless, it gives me hope that the next few years leading up to and including 5790 are especially potent times for moshiach to come.
