כָּל הַחֹדֶשׁ אֵין אוֹמְרִים תַּחֲנוּן

Tachanun is omitted throughout this month.

אַחַר אֲמִירַת הַנָּשִׂיא אוֹמְרִים יְהִי רָצוֹן הַנִּדְפָּס בְּסִדּוּר תּוֹרָה אוֹר

After reciting the [passages recounting the offerings] of the Nesi'im we add the prayer beginning Yehi ratzon, as printed in the Siddur Torah Or.

וְגַם כֹּהֲנִים וּלְוִיִּם אוֹמְרִים אוֹתוֹ

Kohanim and levi’im should also recite it.

אַאַמוּ"ר צִיוָּה לְגִיסוֹ הָרַב מֹשֶׁה האָרעֶנְשׁטֵיין הַכֹּהֵן

My revered father, the Rebbe [Rashab], instructed his brother-in-law, R. Moshe Hornstein HaKohen

לֵאמֹר הַיְּהִי רָצוֹן שֶׁאַחַר הַנָּשִׂיא

to recite the Yehi ratzon after the offering of each of the Nesi’im.

וְאָמַר לוֹ כִּי אֲפִילוּ כֹּהֵן וְלֵוִי צָרִיךְ לְאָמְרוֹ

He told him that even a kohen and a levi should recite this prayer,

כִּי זֶה שַׁיָּךְ לָעִבּוּר

because [souls are sometimes] impregnated [by other souls].
