Answer: The Light is phenomena in which the will to receive senses the upper force, spirituality, the Creator, the force that directs and governs the desire to receive.
The Light is the only power that actually exists. The other force is the desire to receive. There is nothing but these two powers. In other words, a desire to receive is something that is “locked” from within, whereas the Light is open and fills the entire universe.
Inside the desire, there is a tiny spark of the Light with the help of which the desire can connect with the external Light, thus directing the Light’s actions performed on the desire. An aspiration of the will to receive to be similar with the Light allows it to establish connection with the Light, thus triggering the Light’s impact upon it.
Question: Then what is the connection between the books written by Kabbalists and the Light?
Answer: All Kabbalistic books are the stories about the impact of the Light on the desire. There is nothing else besides it. The Light is the Creator, i.e., the force that rules everything. If one wants to approach the Light, one should learn how to build correct intentions on top of one’s desires so that the Light descends and conveys its properties to it, thus making one similar to the Light. In this case, one’s actions become similar to the Light even though one’s desires are opposite to it.
The entire wisdom of Kabbalah is the revelation of the Light to the creation.
