One Can Achieve More on Tisha B'Av Than on Simchas Torah

One Can Achieve More on Tisha B’Av Than on Simchas Torah:
Sefer Avodas Yisroel (on Maseches Avos, Perek 3) writes: “One can be mesaken more on Tisha B’Av, when he is downtrodden, than he can be mesaken on Simchas Torah. One can make this rectification with Torah, tefillah and teshuva. One should not be like the masses who say that they cannot daven during Bain Hametzarim. Of course, they are being foolish. Rather, one must strengthen himself in Torah, tefillah and teshuva, during these days. They are days of teshuva because the 17th of Tamuz was the beginning of the 40 days when Moshe Rabenu asked for mercy for Klal Yisroel, as is stated in the Medrash (Devarim Rabbah 3).
