The Rebbe said, “If you hear only the sound of my voice when I reveal a lesson, it is still a great benefit, even if you do not hear the words. It is written, ‘ Hearing the sound of His word’ (Psalms 103:20). – the sound specifically. Even if you hear nothing, but are merely in the building where the lesson is revealed, you still gain immeasurable good.”
אָמַר: אֲפִלּוּ מִי שֶׁאֵינוֹ שׁוֹמֵעַ דִּבּוּרֵי הַתּוֹרָה שֶׁאָמַר, רַק הַקּוֹל לְבַד, הוּא גַּם כֵּן טוֹב מְאֹד. וְזֶה בְּחִינַת "לִשְׁמֹעַ בְּקוֹל דְּבָרוֹ" (תְּהִלִּים קג), 'בְּקוֹל' דַּיְקָא. וַאֲפִלּוּ מִי שֶׁהוּא רַק עוֹמֵד בַּבַּיִת אֵצֶל הַתּוֹרָה שֶׁאוֹמֵר, טוֹב מְאֹד מְאֹד בְּלִי שִׁעוּר.
