The Book of Numbers is the fourth of the five books and it is the aspect of Zeir Anpin.
The Zohar begins the commentary of the first portion of Numbers, Bamidbar, discussing the creation of Man, Adam. The numerical value for Adam, אדם, is 45, same as the value for the YHVH name revealed at the level of Zeir Anpin יוד-הא-ואו-הא. Zeir Anpin is the ‘child’ of Chokmah (Father) and Binah (Mother).
When God created Adam he gave him the image/forms of the upper and lower levels. All levels were included, Malchut was one of them. He could see from the beginning to the end of the world because his head was in Chokmah and Binah that are the concealed levels, the head.
Zeir Anpin and Malchut are the spiritual and physical bodies. Male and female, left and right, judgment and kindness (Chessed) aspects.
When Eve got separated from Adam, each of them had the aspect of left and right because they inherited these aspects from each other.
Becoming one with another creates affinity and exchange of energies. If we want to come closer to understand another person we need to match his level. Only then we can experience the flow of energies from one to the other. Before we do so, we need to make sure the other person is positive and worth our efforts to make same level connection. It’s an important principal that could help us greatly in life.
The most important aspect of this teaching is about connecting to the Zohar on a higher level that could give us the ability to elevate to the higher spiritual levels and draw benefits into our lives.
