Nissan 30 is the yahrtzeit (anniversary of the passing) of the famed Kabbalist Rabbi Chaim Vital (1542?-1620), author of the mystical work Eitz Chaim. Rabbi Chaim was the leading disciple of Rabbi Isaac Luria (the "Holy Ari," 1534-1572) and the transcriber of his teachings, which form the "Lurianic" Kabbalah.

As a young man, R. Joseph Ibn Migash studied under R. Yitzchak Alfasi for fourteen years. After the latter’s death, he succeeded him as head of the Talmudic academy in Lucena, Spain. His halachic opinions were sought after from afar, and he taught numerous disciples, including R. Maimon, father of Maimonides. Although he did not study under him personally, Maimonides viewed R. Joseph as his own teacher and greatly praised his erudition.
R. Jacob Emden, son of R. Tzvi Ashkenazi—known by the acronym Yaavetz (Yaakov ben Tzvi)—was a great scholar and author who lived in Emden and then in Altona (both cities in Germany). He was known for his zealousness and his willingness to fight for what he felt was right, disregarding any opposition. Among his works is a prayer book with commentaries known as Siddur Yaavetz.

Today is the first of the two Rosh Chodesh ("Head of the Month") days for the month of "Iyar" (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.

Tomorrow is the sixteenth day of the Omer Count. Since, on the Jewish calendar, the day begins at nightfall of the previous evening, we count the omer for tomorrow's date tonight, after nightfall: "Today is sixteen days, which are two weeks and two days, to the Omer." (If you miss the count tonight, you can count the omer all day tomorrow, but without the preceding blessing).
The 49-day "Counting of the Omer" retraces our ancestors' seven-week spiritual journey from the Exodus to Sinai. Each evening we recite a special blessing and count the days and weeks that have passed since the Omer; the 50th day is Shavuot, the festival celebrating the Giving of the Torah at Sinai.
Tonight's Sefirah: Gevurah sheb'Tifferet -- "Restraint in Harmony"
The teachings of Kabbalah explain that there are seven "Divine Attributes" -- Sefirot -- that G-d assumes through which to relate to our existence: Chessed, Gevurah, Tifferet, Netzach, Hod, Yesod and Malchut ("Love", "Strength", "Beauty", "Victory", "Splendor", "Foundation" and "Sovereignty"). In the human being, created in the "image of G-d," the seven sefirot are mirrored in the seven "emotional attributes" of the human soul: Kindness, Restraint, Harmony, Ambition, Humility, Connection and Receptiveness. Each of the seven attributes contain elements of all seven--i.e., "Kindness in Kindness", "Restraint in Kindness", "Harmony in Kindness", etc.--making for a total of forty-nine traits. The 49-day Omer Count is thus a 49-step process of self-refinement, with each day devoted to the "rectification" and perfection of one the forty-nine "sefirot."

How to count the Omer
The deeper significance of the Omer Count
Any other time of the year, it’s just a cracker. Eat it on the night of Passover, and it nourishes your soul.
Because, in truth, all food feeds not only the body, but the soul as well.
That’s because, like everything else, food is a divine creation. It is sustained by a constant flow of energy from its Maker. When we consume food, we metabolize that divine energy and live from it.
The kind of food-energy we consume and the way we consume it has a lot to do with kind of person we become and the kind of life we end up living.
If we eat foods sustained by energy hopelessly distorted, corrupted, and disconnected from its origin, they pull us down with them and it becomes harder for us to keep in touch with our own soul. These are the foods that are not kosher.
But then, even the energy of kosher food needs to be reconnected to its origin. And we do that by investing whatever energy we’ve gained from this food into G‑dly deeds--a.k.a. mitzvahs.
Matzah on Passover is the exception. On the night of Passover, it’s not just a mitzvah to eat matzah; the matzah itself is a mitzvah. It’s already intimately connected with its source.
So that, rather than us having to reconnect this food, it reconnects us, nourishing both body and soul with divine light, carrying us to heights we could otherwise never achieve.
And so, writes Rabbi Shmuel of Lubavitch, matzah on Passover--especially on the first night--not only nourishes your divine soul, it softens up the animal instinct within you. Your inner beast becomes open to knowing something greater than itself.
At the very least, he writes, it allows your divine soul some respite.
As it turns out, matzah on Passover is not just food for the soul, it’s potent medicine for the human animal.
