Question: If our world is the lowest of the worlds and if we can start climbing the ladder of spiritual steps with the help of the wisdom of Kabbalah, why then are millions of people walking about this lowest degree never reaching even the starting point of spiritual ascent?
Answer: There are five spiritual worlds: Atzilut, Beria, Yetzira, Assiya, and Adam Kadmon. We are at the lowest degree, in the corporeal world. All of the 125 degrees that are above us are levels of transformation of reality.
Do you wish to change reality? If yes, you need a screen. A screen is defined as the measure of connection between me and the Light, the Creator. I must connect myself with the Light, the Creator, with the help of the screen.
Then, by means of various actions I perform with the screen, I will be able to create various forms of reality. Besides, these forms are alive, just like people whom I see right now. Yet, at the moment, I am not the one who is creating this reality; such perception is given to me by nature.
However, when I start ascending in spirituality, I act as the Creator does. I create each degree, all its still, vegetative, animate, and speaking levels. I create this reality; I form and support it instead of the Creator. However, who is this “I?” The “I” is the one who possesses a screen.
