Yud - 10th Letter of the Hebrew Alphabet
The letter YUD signifies the number ten. It is the only letter that is suspended in midair and singular in form.
In its singularity, YUD signifies the Oneness of God, who is indivisible.
YUD, being the smallest of all the letters in the Hebrew alphabet, signifies the importance of humility.
The number ten denotes the ten Divine forces (sefirot) that form the Tree of Life. It is believed that these forces are the essence of all created matter.
Yom Kippur (the Day of Atonement), the holiest day in the Jewish calendar, is heavily associated with the letter YUD. It falls on the tenth day of the month of Tishrei. It marks the end of the Ten Days of Awe, further emphasising the significance of the YUD, so small and yet so powerful.
YUD is the first letter of yom (day). In reference to the Creation story, this signifies the power of a single unit to turn one day into a whole week, demonstrating that greatness is achieved through humility.
The name of God and Israel both begin with the letter YUD. It is said that the people of Israel, the Chosen people, were the smallest and most humble of nations.
