This letter develops the idea that exile and concealment are not the end of holiness but part of a divine process leading to revelation. It offers a Chassidic lens for understanding how a day like Tu B'Av can carry joy even after destruction.

But when the Israelites were exiled to be among the nations—and the attachment and root of the Israelites is in the rank of the supernal face (panim)—this became a total exile. Of this our Sages, of blessed memory, said: “When they were exiled to Edom, the Shechinah went with them.”)) Now, with one opposite the other, there are “ten crowns of impurity.” From these issue the souls of the heathens, also comprised of precisely those ten ranks. And it is common knowledge that which has been stated in Sefer Hagilgulim on the verse “That man rules in man, to his evil,” that it refers to the mystery of the Shechinah’s exile in the kelipot in order to vivify them, and to empower them to rule, now, in the time of the exile; but it is “to his evil….” And that is why the heathens dominate now over Israel. For the souls of the heathens are of the kelipot, in which the Shechinah is vested in a state of exile. Though this requires extensive exposition (as to) how and what, it is, nevertheless, fact. Despite this, the kelipot and heathens receive their nurture and vivification only from an aspect extended to them, of the achorayim of holiness, “as with one who casts away behind his shoulders.” And even that is by way of numerous and immense contractions and curtailments until this radiation became vested in the materiality of this world and diffuses wealth and honor, and all physical pleasures, to the heathens. The Israelites, however, elicit from the aspect of the supernal face, as it is written: “May the L–rd make His face shine upon you,” in each one according to the root of his soul, even up to the peak of levels.
