Question: How does the spiritual Masach (screen) work?
Answer: On one hand, the Masach doesn’t let the upper Light enter our ego and work with it. This means that it keeps and sustains the restriction of the desire.
On the other hand, it gradually adjusts the attribute of bestowal of the upper Light to our desires, and by detaching us from our previous desires, it enables us to acquire new desires for love and bestowal. A Masach is the most important part of the soul.
From the Kabbalah Lesson in Russian 12/18/16
The Screen Is Maximum Equivalence To The Giver
The Screen Is Your Contribution To The Spiritual Reality
The Screen Of My Reality
