The Torah, “Leviticus,” 21:1 – 21:3: And the Lord said to Moses: Speak to the Cohanim (priests), the sons of Aaron, and say to them: Let none [of you] defile himself for a dead person among his people except for his relative who is close to him, his mother, his father, his son, his daughter, his brother, and for his virgin sister who is close to him, who was not [yet] with a man for her, he shall defile himself.
In spiritual work, a person is always found as an intermediary component between higher and lower characteristics. The higher characteristics of the priest are direct to the Creator.The lower characteristics are those that hold and support a desire that is directed toward the Creator and proceed according to a hierarchy directed downward. A person is based seemingly upon these desires, each one of them is connected to him on his level when he nullifies himself and is included in his yearning for the Creator. With this, they justify their mission.
In creation, nothing was created besides desire. So, our work is to direct it toward bestowal, toward the Creator, just as He directs His action toward us, and then we attain adhesion.
A priest (Cohen) is a characteristic that is ready to raise all of the desires that stand below according to a hierarchy and direct them toward connection with the Creator.
The Levites are the executing mechanism, shaping the desires that are found under the priest. They understand the priests and know how to carry out his instructions.
Israel are even lower desires that can be subservient to the Levites and through them to the priest (Cohen), and they constitute a connection between the higher desires and the desires called the “nations of the world,” and below the desires of the nations of the world are the desires of the animate, vegetative, and still.
All of the desires must be directed together toward general unity, and when it is attained, then within it the characteristic of full mutual bestowal is discovered. Imagine for a long time you are painstakingly gathering something, and suddenly it begins to glow from within. This means that the power of the desires attains this kind of unity when it begins to shine. This is the discovery of the Creator.
In other words, this mutual unification among the characteristics of the creatures happens when the Creator is discovered. He shines through the entire pyramid according to the law of equivalence between the desire and the Light. This is the goal of our development, whereas the goal of our existence is to attain this state and to advance toward something that, in the meantime, is still not known to us.
