The Esoteric Meaning of Numbers - Numerology 107

Who knows SEVEN?
I know SEVEN.
Seven are the days of the week.

As discussed last time, six is reality and we see six dimensions, but we believe that there is one more. A seventh dimension. The Maharal explains it as a room. In a room, there are four walls, a ceiling, a floor, and an interior space which makes seven. That seventh dimension is the presence of G-d in this material world. Some call it nature, randomness or luck. There's a reason that there's a saying, "Lucky number seven". They call it luck. We call it Hashgacha/Yad Hashem.
Because it's a representation of spiritual in the physical world, the number seven is a holy number. That's what the days of the week and Shabbos represent. We work for six days, and the seventh day, Shabbos, is not just a spiritual day, but even though we officially do nothing on that day, as the gemara says "minay mitbarchin kula yoma" from Shabbos comes the bracha for the rest of the week.
Which mitzva is Shabbos? It's the 32nd mitzva in the Torah. 32 is the gematria of "lev"/heart, Shabbos/number seven is at the heart of all the mitzvos and the entire universe.
In addition to Shabbos, Pesach and Sukos are seven days long (in EY), there are seven heavens, seven sefiros, seven brachos at a chupa, seven years of shmitta and seven shmitta cycles in a yoveil. Dovid, the first king of Yehudah, was the seventh son and the seventh generation (I'm still trying to figure out what that means). What I do know is that malchus is the seventh of the sefiros. Erev Shavuos is malchus she'b'malchus. Consequently, as mentioned before relating Aharon to the number five, in the ushpizins, Dovid Hamelech is the seventh. Dovid is the one who was beloved to Hashem. "Ani Tefilla". There are seven musical notes (strings of David's harp). Tishrei, the month with the most and holiest of our holidays, is the seventh month. On Yom Kippur, the Kohein Gadol sprinkles the blood seven times. In the Bais Hamikdash, there were seven cups on the menorah (I spelled it with the "h" so that it would have seven letters). There were three on each side facing the one in the middle which miraculously never went out.
On Sukos, when we shake the lulav and esrog by the pasuk of Hodu laHashem kee tov, we shake in all six directions, but there are seven words in the pasuk, the seventh word is Hashem and when saying Hashem's name we don't shake the lulav at all. This symbolizes our recognition that there is a seventh dimension that we know is there, and is everywhere. We know it exists but we can't pinpoint it or point to it.
We have to make our best efforts in this world, but we also have to understand that ultimately, the end result is all in Hashem's hands. "Man tracht, Gut lacht" Man plans and G-d laughs. That, I believe, is also the connection to the corresponding hebrew letter to the number seven, the letter zayin, which happens to be the letter that reprents the male. The word zayin or zan has two meanings. Klai zayin are tools or weapons of war, and to be zan means to provide food for. These are the two primary roles associated with men. These are also two of the most prime examples of the concept that we were just discussing, that man has to put forth his best efforts, but ultimately, the results are all b'yad Hashem.
