כַּמָּה וְכַמָּה חֲסִידִים חָשְׁבוּ יוֹם בּוֹאָם לְליוּבּאַוִויטְשׁ לְיוֹם הוּלֶדֶת שֶׁלָּהֶם Many chassidim used to consider the day they first came to Lubavitch as their birthday. מוֹרִי הָרַשְׁבַּ"ץ בָּא בַּפַּעַם הָרִאשׁוֹנָה לְליוּבּאַוִויטְשׁ My teacher, the Rashbatz, arrived in Lubavitch for the first time אוֹר לְיוֹם שִׁשִּׁי פָּרָשַׁת מִשְׁפָּטִים שְׁנַת תּר"ח on the Thursday night of Parshas Mishpatim, 5608 (1848). וּבְכָל שָׁנָה וְשָׁנָה הָיָה עֵר כָּל אוֹתוֹ הַלַּיְלָה Every year, [on that evening,] he would stay awake throughout that night, וּמְכַוֵּן לְהָנִיחַ תְּפִלִּין בָּהּ בְּשָׁעָה אֲשֶׁר נִכְנַס לְהַצֶּמַח צֶדֶק בַּפַּעַם הָרִאשׁוֹנָה and [in the morning] put on his tefillin at precisely the hour that he had entered the study of the Tzemach Tzedek [for yechidus] for the first time.
