R. Eliezer Yehuda was a well-known contemporary halachic authority who resided in Jerusalem. His halachic decisions are held in high esteem, especially in the field of medical practice. Many of these decisions appear in his 22-volume set of responsa titled Tzitz Eliezer.

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

The sages say that all is in the hands of heaven except for the awe of heaven.
Which puts all the power in your hands.
Because if there is no awe of heaven, heaven is bankrupt. It owns nothing—not you, not your world, not anything at all.
That being so, the greatest power you have is your ability to surrender the delusion that you have any power at all, to shift from serving yourself to serving heaven. To experience awe.
Surrender yourself to heaven, and the heavens are utterly under your command.
