Have Mercy on Yourself and Spread Chassidus!
Chof Elul, 5776
Think about it: The Arizal stated that specifically in these last generations it is permissible and a mitzvah to reveal the wisdom [of pnimiyus hatorah]. Moshe Rabbeinu, raya mehemna [the "faithful shepherd" quoted in Zohar], stated that "Yisroel will leave the golus with compassion because one day they will taste from the tree of life, namely, the sefer of Zohar." Hashem reveals his secrets through the Baal Shem Tov, his students, and his students' students, up until our generation, just so that the geulah will come, [when we will experience] redemption from the yetzer hara and shibud malchiyos, and [so that] all this should take place "with compassion."
[Accordingly,] it should have been that anyone with the necessary measure of influence would cry out with an inner voice: Jewish brethren! Have mercy on yourselves and on Klal Yisroel and spread [pnimiyus hatorah], the Torah and words of Elokim chaim! [They would further] inform [others] of the statement of R. Chaim Vital that [lacking to study pnimiyus hatorah] delays the ketz of the geulah. In other words, they are holding back themselves, Klal Yisroel, and the shechinah, kevayochol, in golus!
