I already wrote to you on Friday of Parshas Yisro — when I had already heard of what had passed over you — and that you should see to come here immediately without delay. And at present, my son, the delight of my eyes, the friend of my soul — I ask of you that you give no thought to this at all — and remove from your mind all worries and black melancholy. Only strengthen your soul in Hashem Yisborach. Hope to Hashem and He will save you [cf. Tehillim 27:14] — for we have no one to lean upon except His abundant mercies. And you already know a little that this world is full of sufferings, and all its days are anger and pain. And there is no place to flee from it — except to Hashem Yisborach and to the Torah that gladdens the heart and restores the soul [cf. Tehillim 19:8]. And beyond this it is impossible to elaborate, as I am in an open field — and salvation belongs to Hashem.
Behold — thus speak the words of your father, who longs to see you speedily.
The utterance of the lowly Nussun, son of our Teacher the Rabbi Naftali Hirtz — may his light shine and radiate.
Overview: This brief letter is a second wave of consolation after an unspecified trouble that had befallen Reb Nussun's son Yitzchok — the first letter (written on Friday of Parshas Yisro, not preserved) having already urged him to come home to Breslov. The present letter, written three weeks later on Parshas Terumah, repeats the call while delivering its essential teaching in one sentence: there is nowhere to flee from the sufferings of this world except to Hashem and to the Torah that gladdens the heart and restores the soul. The printing update — 62 prayers now complete — continues the running chronicle of Likutay Teffilos across Letters 15–18.
Across four consecutive letters spanning Kislev to Adar Aleph 5584, we can track the printing of Likutay Teffilos in real time: printing began (Letter 15, Kislev); five signatures complete, sixth under way (Letter 16, Teves 7); Prayer 55 reached, press halted for lack of ink oil (Letter 17, Shevat 8); sixty-two prayers complete (Letter 18, Adar Aleph 3). This is an unprecedented documentary record of the physical creation of a foundational Breslov text.
