Golus has two Yeridos and Geula has two Aliyos. This is true in general: 1) Geula from Mitzrayim 2) the Geula of Moshiach and in particular: in each of these two Goliyos there are two levels of descent and two levels of ascent 1) like ascending from limitation of thought 2) Ascending from limitation of speech. Dibur is more Tzimtzum than Machshava, yet it’s correction and Aliya happens at the end (and the darkest period) of the Golus [why?].
