Answer: The spiritual root of the number 10 is that after 10 degrees the root of this calculus is revealed. Therefore, the essence of the attitude of the Creator to the creation, and vice versa, is manifested in the ten. In other words, it is necessary to go through 10 degrees from the creation to the Creator and from the Creator to the creation in order for one to feel the other.
Question: How is the number 10 related to the four-letter name of the Creator “Yod-Hey-Vav-Hey”?
Answer: Ten or four are the same. If we briefly reveal the quality of the Creator and the quality of creation, then the relationship between them can be combined into the four-letter name of the Creator, that is, into four stages, or they can be expanded and explained in 10 stages. But practically it is the same thing.
