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.
There are two sorts of inner convictions of the soul, this thing we call faith.
Unbound by the confines of space and time, your soul sees a reality your mind cannot fathom. From that vision seeps down a conviction that G-d is with you, that He is good, and that there is really nothing else but Him.
Not because you understand. But because your soul sees that this is so. And she sees with a clarity and certainty the flesh eye could never attain.
Nevertheless, a higher vision means there are two and not one: There is you and there is the vision you perceive. And if there are two, two can be separated.
So that, when darkness and confusion swells and storms, threatening to rip you away from your G-d, a higher vision is not enough.
That is when you need to reach to the very core of your soul. Not to that place in the soul that sees G-d, but to the essence of the soul that is truly a part of G-d.
To say, "This is my G‑d. I am His, He is mine, and we are one."
"And so, nothing can stand between us."
