Before we begin reading The Zohar, we need to prepare ourselves with an internal feeling that we are within the group. We will then be similar to that same group of the Kabbalists who wrote The Zohar and will have an easier time understanding what they convey to us.
Understanding comes as a result of the Light’s influence. The Light acts upon us from within the connection between the souls of ten Kabbalists who together existed in the final corrected state, meaning in the final corrected connection between one another. When they corrected the connection between them to such a degree that nobody had a single uncorrected desire to receive pleasure, then between themselves they revealed the Upper Light called “Zohar,” the Light originating from the Rosh (head) of Arich Anpin, which is the Light of Infinity.
Hence, if we try to reach the same relation between us as the authors of The Zohar had, we will attract the Light from the same state which they attained. This Light can also create the connection between us as it is said, “One who makes peace in the Upper One, makes peace in us.” This is precisely what we should expect from reading The Zohar.
