סַבְלָנוּת

The primary totality of all of creation — from the beginning of atzilus [emanation] to the end of the central point of this physical world — all of it exists in order to show and reveal His mercy, blessed be He. It follows that in every thing in the world there is clothed and contracted His mercy, blessed be He; and in that thing there is so much mercy — for His attribute of mercy required that this thing should be in this particular form and nature and power and manner of conduct; and this thing should be in this form and nature, etc., like this — all according to the requirement of His mercy, blessed be He; for mercy is the root of all creation — for everything was created in order to reveal His mercy, blessed be He. And from this a person can understand how everything that passes over him and is conducted with him must be received with love and joy — and to believe with complete faith that "whatever the Merciful One does is for the good" [Aramaic: kol mah d'avid Rachmana l'tav avid — Talmud Bavli, Berachos 60b] — for Hashem Yisborach governs His world with loving-kindness and His creatures with mercy; for His mercy, blessed be He, is the root of all creation as above.

The more sufferings a person has — meaning from more people — through this the body is more subdued and the soul grows more; and through this he can the more raise, lift, and elevate many to their root.

Against [i.e., in exchange for] one instance of attachment to Hashem Yisborach — any dimension of attachment in thought or in another dimension — certainly all sufferings are as nothing; and through them themselves one draws closer and attaches more to Hashem Yisborach.
