Answer: Imagine that there are two windows before us, like on a computer screen. In one of them we see a system where we are perfectly connected with one another. It is called the “World of Infinity.” In the other window we see the system that is now before us, where hatred governs instead of love. This system is called “this world.”
These are two different systems. The World of Infinity lives and exists; it is called the first (Aleph) and the third (Gimel) states of reality. This is the only state created by the Creator, in which He exists.
All other states, from the World of Infinity to our world, the 125 degrees of connection between us (125 states), are for us to use to gradually ascend. All the states except for Infinity are called “worlds,” meaning concealment, hiding. The same World of Infinity, but a more concealed one, vaguer, and not fully recognizable is called the World of Atzilut. An even foggier one is the World of Beria, and so on.
Every world is similar to the world above and below it in every part and detail. The only difference is the degree of revelation of the Light in it. The less Light, the darker it is. It is similar to when we see things well during the day and everything is clear, but at night it is dark, yet there is little difference between darkness and light.
In other words, we exist in that same state, referred to as the “World of Infinity,” only 125 degrees of concealment are blocking it from us. And because the concealment is so large on the last degree, where we exist in our world, we are considered completely separated from spirituality. We do not even have the slightest sensation that there are states and degrees between us and the World of Infinity, as if we only exist here, and there is nothing else.
We exist in this world, in our “window” on our “screen,” but there is another “window” on the same “screen,” the World of Infinity. For this reason, when we try to treat each other properly, like in the World of Infinity, as if we already were there (even though we are not yet capable of it), by doing so we make ourselves similar to the World of Infinity, we as if desire to reach it.
When we aspire to it like infants who want to become adults, we evoke the Surrounding Light (Ohr Makif) from the same World of Infinity. This Light is the Light that Reforms and brings us closer to the World of Infinity.
The same principle works everywhere: When I aspire to attain a source of energy, I evoke a large influence through my aspiration to come near it. These are precise laws of physics operating here, there is nothing imaginary or mystical here.
