Question: How important is it to divide the pleasure that is received from the Creator into portions? After all, it is no secret that if you spend a lot of time in the sun, you can get burned and not tanned.
Answer: First, we need to prepare our desire for the right contact. Accordingly, we must first reject all pleasure, restricting (Tzimtzum) it and not allowing it to enter into us.
Then we must build a screen (Masach) that will send the pleasure back. Only after that will it become possible to come in contact with it and gradually begin to receive pleasure in measured amounts called Nefesh, Ruach, Neshama, Haya, Yechida, and so forth.
Everything comes gradually. To the degree that we build a resistance within us called a screen, we can discover the pleasure that is found between us. Above us, there is a system that makes it possible for the Upper Light to reach us only in the same amount that a particular protective system exists within us called a Masach.
Question: How do the brain and nerves of a Kabbalist withstand the feeling of pleasure that is millions of times greater than the pleasure of an ordinary person? Is this not reflected mentally?
Answer: I tdoes not affect the mind because a system exists that protects everything and does not allow the person to be harmed by the Upper Light in any way. What is called a Pulsa de Nura (light shock) is just something to “horror story.” So don’t worry, nothing will happen; no one has ever been harmed by the wisdom of Kabbalah. It is only those who hate it who intentionally disseminate rumors like this.
