In Shir Hashirim, King Shlomo movingly depicts Hashem's profound love for the Jewish people. "
B'tzilo chimaditi v'yashavti.
I desired his shade and I have dwelt there, his fruits are sweet to my palate." According to the Midrash, this refers to the
mitzvot
of
sukka
and
lulav
, which are our central methods of connection to Hashem on Sukkot. Why did Hashem give us two
mitzvot
on this holiday
? Why was one not adequate?
The Shem MiShmuel explains that man is a dual combination of mind and heart. This is reflected in the ten
sefirot
, which are expressed on both intellectual and emotional levels. Moshe, the paragon of intellect, and Aharon, the embodiment of emotion, were the founding fathers of the Jewish nation. Moshe's role was primarily
moach,
intellect, bringing Torah to Jewry, Aharon's purpose was
lev,
emotion, achieving harmony between man and Hashem. His prayers and service in the M
ishkan
were the focal point of Yom Kippur. Additionally, he pursued peace and mended troubled relationships between people.
The Torah emphasizes, "
Hu Aharon U'Moshe
," the role of Aharon was equal to Moshe's. The Shem Mishmuel notes that perfection of intellect is intertwined with perfection of emotion. Both are needed to attain
sheleimut
. Indeed, when we examine the lives of our Torah giants we see this combination of wisdom of mind and heart.
The Gemara writes that the
mitzva
of
sukkah
serves as a remembrance to the Clouds of Glory, which were given in the merit of Aharon. The
sukkah
signifies the life and essence of Aharon. Aharon personified peace, fulfillment, humility, and total subservience to Hashem. This is the
sukkah
- modesty, harmony and completion. The
lulav
represents the teachings of Moshe. It is a straight line that corresponds to the direct intellectual logic of Torah. Both
mitzvot
help us tap into the dual essence of the holiday.
Rosh Hashana is the head of the year. It signifies a new beginning and corresponds to the soul of Moshe, who personified intellect. It is a day to think about our past deeds, make a personal reckoning, and plan for the future. Yom Kippur is
lev,
emotion. It symbolizes Aharon Hakohein. The Torah writes, "
B'zot yavo Aharon el hakodesh
." It links Aharon specifically with the service in the Mishkan. Rav Soloveitchik notes that the essence of Yom Kippur was the
avodah
of Aharon, who was the paragon of
ahavat
Hashem and
ahavat
Yisrael.
On Rosh Hashana we rededicate our intellect to Hashem. On Yom Kippur we reignite our souls to
ahavat
Hashem. All this culminates with Sukkot - the pinnacle of joy and completion as we celebrate the melding of intellectual, emotional, and spiritual purification.
