On the 13th of Tammuz of 1927, the sixth Lubavitcher Rebbe, Rabbi Yosef Yitzchak Schneersohn, received the documents authorizing his release from a sentence of exile to Kastroma in the interior of Russia. The Rebbe was actually notified of his release on Tammuz 12, but since that day was a legal holiday, the Certificate of Release freeing him to travel home was issued only the next day. Thus both the 12th and 13th of Tammuz are celebrated as a "festival of liberation" by the Chabad-Lubavitch community. (For more on the Rebbe's arrest and liberation, "Today in Jewish History" for yesterday, Tammuz 12).
In Chabad practice, Tachanun (confession of sins) and similar prayers are omitted today.
Blind faith is intellect’s most deadly foe. Intellect that would surrender to faith has forfeited its very nature.
True faith is intellect’s most vital partner. To travel beyond its boundaries, intellect must find a vision that transcends itself.
That is the meaning of true faith: A perspective that surpasses the field of intellect’s vision, a sense that there is something not only unknown, but unknowable; something before which all our knowledge is an infinitesimal point of nothingness.
And so, the mind that fears faith will choose a truth with which it is most comfortable, while the mind that has found a partner in faith will choose truth that is absolute.
