יֵשׁ כַּמָּה שְׁטוּתִים וּבִלְבּוּלִים הַמִּתְדַּבְּקִים וּמִתְחַבְּרִים בְּהַמֹּחַ, וּבִפְרָט בִּלְבּוּלֵי הָאֱמוּנָה.
Rabbi Nachman's Wisdom, trans. Aryeh Kaplan, Jerusalem. Breslov Research Institute, 1973
Many types of foolishness and confusion attach themselves to the mind – in particular, confusion concerning faith.
וְעַל־יְדֵי הַשֵּׁנָה נִפְרָדִים מֵהַמֹּחַ. וּבְיוֹתֵר מוֹעִיל הַשֵּׁנָה לָאֱמוּנָה כַּנַּ"ל.
Rabbi Nachman's Wisdom, trans. Aryeh Kaplan, Jerusalem. Breslov Research Institute, 1973
Sleep removes this confusion from the mind. Sleep is especially beneficial for faith.
