Yod has the numeric value 10. The base 10 number system is universal. Just as Yod is part of all of the previous letters of the alphabet (as a component), so Yod is part of all of the numbers.
In the Jewish mystical tradition, Yod represents a mere dot, a divine point of energy. Since Yod is used to form all the other letters, and since God uses the letters as the building blocks of creation, Yod indicates God's omnipresence. Yod is considered the starting point of the presence of God in all things - the "spark" of the Spirit in everything."4
Note: The Hebrew alphabet is made up of 22 letters. Each letter has a number equivalent, thus every word has a numerical equivalent as well. The Hebrew alphabet is rich in meanings.
