G-d bless you all!
Greeting and Blessing:
...We will briefly dwell here on a point which distinguishes this year's Rosh Hashanah from others, namely, that this year Rosh Hashanah is the "head" of a Leap Year. And herein, too, a further distinction:
Not all Leap Years in our Hebrew Calendar are the same. This year has the distinction of having the maximum number of days that any Leap Year can have - 385 days.
On a previous occasion, it has been pointed out at some length that the purpose of a Leap Year in our Torah-Calendar is to make up for the "deficiency" in the days of previous years, in order to bring into harmony the Lunar year with the seasons of the year (determined by the Solar year), though the annual seasons are also, of course, determined by the Creator, as Torah declares: "(The seasons of) sowing and reaping, cold and heat, summer and winter, shall not cease."
Moreover, not only does the Leap Month make up the deficiency of the past, but it also gives an "advance" on the future.
This year, as noted above, the Leap Year is of maximum dimension.
It is a well-known principle that all that we see or find in the realm of matter, in the physical world around us, are replicas of the spiritual counterparts in the sublime Supernal Worlds from which they descended. The same is especially true also in this case.
The order of having to make good and equalize the number of days, in the plain sense, in the material world, is due to the fact that this is the order in the spiritual realm, where "each day has its task to perform." This is also the special instruction for us in respect of the task each has to accomplish in the areas of "Man unto toil is born," "All your actions should be for the sake of Heaven," and "Know Him in all your ways"
...In light of the above it is clear that the preparations and service expected of a Jew for the new year-in the days before Rosh Hashanah, particularly during the days of Selichos [penitence]; on Rosh Hashanah itself; and during the Ten Days of Teshuvah (Repentance), especially on the Holiest Day (Yom Kippur) - have to be on the order of the Leap Year: To make good those aspects of the service where there has been a deficiency in the past year, and bring perfection into the other areas, indeed even to the extent of an "advance" on the future.
And all this should be carried out in the fullest, maximum measure.
Moreover, as has often been emphasized - since G-d requests and expects a Jew to do a certain task, it is certain that He has provided him with all the necessary capacities and means to carry it out in actual fact, and, furthermore, to do it with joy and gladness of heart, and all matters of Divine service should be carried out.
Our Sages of blessed memory say that the Ten Days of Teshuvah [from Rosh Hashanah through Yom Kippur] are the time referred to in the verse, "Seek G-d when He is found, call on Him when He is near." This "nearness" is described as the "near-ness of the Source of Light to its spark."
And comes after the auspicious days of the month of Elul, when the "King is in the field" and shows a gracious countenance to all who come out to meet Him.
May G-d, the Source of Light and Source of Blessing, indeed be gracious to everyone, man and woman, and bless them with Hatzlocho [success] to carry out the said service in the best, maximum way, thereby carrying out in the fullest measure the realization of the ideal for which we pray in our Rosh Hashanah and Yom Kippur prayers: "And reign, Thou alone, O G-d, our G-d, over all Thy creatures..." by acclaiming Him as Our G-d, in response to His request, "Make Me King over you," and involving also all creation, thus bringing about His Kingship over all and everywhere,
So that He will, also in a revealed manner, "work relief in the midst of the earth,"
Especially in light of the continuation of the said prayer that "...on Mount Zion, the abode of Thy Glory, and in Jerusalem, Thy Holy City,"
Which are always the "abode of His Glory and Holy City", also in the present days of the Golus -
G-d's reign be revealed, in the true Re-demption through our Righteous Moshiach,
With esteem and blessing for Chasimo uGmar Chasimo Toivo Leshono Toivo uMesuko (may you be sealed and have a final sealing for a good sweet year)
