Hayom Yom 17 Teves - We do not study Torah Nittel night

מַה שֶׁנּוֹהֲגִים שֶׁלֹּא לִלְמוֹד בְּנִיתְּל, שָׁמַעְתִּי מֵאַאַמוּ"ר הַטַּעַם I heard from my revered father, the Rebbe [Rashab], that the reason that one customarily refrains from studying [Torah] on nittel night שֶׁהוּא כְּדֵי שֶׁלֹּא לְהוֹסִיף חַיּוּת is to refrain from adding vitality [to the kelipos]. פַּעַם אָמַר אַאַמוּ"ר Once my revered father, the Rebbe [Rashab], said: דִי מַתְמִידִים וואָס דִי אַכט שָׁעָה אִיז זֵיי נוֹגֵעַ בְּנֶפֶשׁ, האָב אִיך נִיט האָלט “I do not care for those scholars who are so [unduly] diligent that the loss of those eight hours3 touches their very souls.” וְהוּא רַק עַד חֲצוֹת לַיְלָה [We refrain from studying] only [from sunset] until midnight.
