If people made a habit of sharing good news, they would have less—or no—need to set up bonds of communication about opposite of good news.
By the Grace of G‑d
3 Kislev, 5720 
Greetings and Blessings!
After a long break, your letter of 2 Kislev arrived, in which you write of your financial straits.
As I have written in the past to a number of people, if they had made a habit of sharing [their] good news and writing about it frequently, they would have had less — or no — need to set up bonds of communication by writing about things that are the opposite of good news. This is self-evident.
At any rate, the classic counsel [for the subject of your letter] is to contribute generously to tzedakah. No matter how difficult this may be, one ought to donate at least a few cents more than one was formerly accustomed to giving. One of the propitious times for doing this is every weekday before the morning prayers.
Moreover — and this is the essence — one should strengthen oneself in one’s trust in G‑d, “Who provides nourishment and sustenance for all,” “with grace, with kindness, and with mercy.” [Trusting in this provision] is particularly linked to the concept of Divine Providence which, as is explained in the teachings of Chassidus, applies to the life of every man and woman, down to the finest detail. As expressed in the wonderful teaching of my revered father-in-law, the Rebbe [Rayatz], which appears in HaYom Yom, in the entry for 28 Cheshvan, this [Divine Providence relating to every detail] “brings to completion G‑d’s grand design [in the mystery of all Creation].” See there. And firmly placing one’s trust in Him intensifies all of this.
Especially since we are now in the month of Kislev,4 and this year is the two-hundredth anniversary of the passing of the Baal Shem Tov, much more will be added by increasing, in particular, one’s study of the inner dimension of the Torah, which in our era has been revealed in the teachings of Chassidus — the “Tree of Life, where there is no problematic query,” nor any obscuring and concealment [of the Divine Countenance].
With blessings for good news in all the above,
