Monday is the sixth day of Week 18 and the twenty-seventh day of the cycle of Tiferet (Balance/Beauty), Yesod shebeNetzach shebeTiferet, Foundation within Victory/Endurance within Balance/Beauty.
Monday is also the fifteenth day of the sixth 22-day cycle of the year, related to the letters Kaf and Lamed. The following excerpts from Chapters 112 and 119 of the Book of Psalms are connected to the fifteenth letter, the Samech:
סָמוּךְ לִבּוֹ לֹא יִירָא
His heart is steadfast, he will not fear
15 They obscured the view of all the earth, and the earth became darkened, and they ate all the vegetation of the earth and all the fruits of the trees, which the hail had left over, and no greenery was left in the trees or in the vegetation of the field[s] throughout the entire land of Egypt.
16 Pharaoh hastened to summon Moses and Aaron, and he said, "I have sinned against the Lord your God and against you.
Now this is a general principle in the whole realm of holiness: Holiness (קדושה) is only that which derives from Chochmah, called קודש העליון — “supernal holiness.”
Its very existence is nullified in the light of the blessed Ein Sof which is clothed in it, and it is not a thing apart — as explained earlier.
Therefore, this faculty is called Chochmah, which consists of the two words כ׳׳ח מ׳׳ה (the power of humility and abnegation).
This stands in direct contrast to the kelipah and sitra achra...
It is a mitzvah to kill minim and apikorsim... When, by contrast, a Jew commits transgressions, but does not maintain his wickedness continually, merely occasionally sinning for his own personal satisfaction - e.g., one who eats non-kosher food for pleasure - it is a mitzvah to save his life, and it is forbidden to stand idly by when his life is threatened.
The book Torah Or now printed...contains maamarim, most of them from 5556 (1796) until the end of 5572 (1812). Our Master,1of blessed memory, carefully examined and edited many of these and agreed to have them published. The book is comprised of two parts: The first is on two2 of the Five Books of the Chumash, Chanuka and Purim, with several discourses on Shavuot (time of Giving of the Torah) in parshat Yitro and a few for Pesach included in parshat Vayakheil. The second part (with G‑d's help, will be) on the last three Chumashim, Shir Hashirim, the Festivals, Rosh Hashana and Yom Kippur...The name of the author is fitting:Schneur, (literally, "two lights"), just as v'ahavta ("you shall love") in numerical value is twice that of the word or,3 "light."
