The 9th plague to strike the Egyptians for their refusal to release the Children of Israel from slavery -- a thick darkness that blanketed the land so that "no man saw his fellow, and no man could move from his place" (Exodus 10:23) -- commenced on the 1st of Adar, six weeks before the Exodus.

Adar 1 is also the yahrtzeit (anniversary of the passing) of the great Halachist Rabbi Shabtai Hakohen Katz (1621-1663?), author of the Siftei Cohen commentary on Rabbi Yosef Caro's Code of Jewish Law. He is known as "Shach" -- an acronym of the name of his work, which serves to this day as a primary source of Halachah (Jewish law).

On this date, in the year following the Holy Temple’s destruction, G‑d tells Ezekiel to take up a lamentation for Pharaoh, king of Egypt, foretelling his downfall in the hands of the Babylonians.

Today is the second of the two Rosh Chodesh ("Head of the Month") days for the month of "Adar II" (when a month has 30 days, both the last day of the month and the first day of the following month serve as the following month's Rosh Chodesh).
Special portions are added to the daily prayers: Hallel (Psalms 113-118) is recited -- in its "partial" form -- following the Shacharit morning prayer, and the Yaaleh V'yavo prayer is added to the Amidah and to Grace After Meals; the additional Musaf prayer is said (when Rosh Chodesh is Shabbat, special additions are made to the Shabbat Musaf). Tachnun (confession of sins) and similar prayers are omitted.
Many have the custom to mark Rosh Chodesh with a festive meal and reduced work activity. The latter custom is prevalent amongst women, who have a special affinity with Rosh Chodesh -- the month being the feminine aspect of the Jewish Calendar.

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."
