My Answer: When we read The Zohar together, we strive to unite. We gather in a group so that there are no difference between an advanced student and a beginner, a prominent one and not. Together in a group we are all equal.
Each of us may be in a certain state: one just started and doesn’t fully comprehend where he is, while another has studied The Zohar for some time and has already gained a certain picture from it. Yet both undergo different states. Perhaps today a person feels especially attuned and inspired, but there are times when he is unable to tune in at all, as if unconscious. It may be that yesterday there was great clarity, and today that person is unable to collect his thoughts.
Therefore, everything depends on the collective mass of those who study together, and how well, through a unified effort, they are able to feel that this mass contains everyone within itself. It turns out that those who have sharp clarity today help those who are now lifeless. Moreover, both benefit from each other.
As a matter of fact, the person now inspired lacks the force of egoistic desire (Aviut), but receives it from those currently in the dead state and vice versa. In this way, when there is great inspiration and Aviut at the same time, then together in unison we help each other to receive an opportunity for advancement. Thus, when we connect and bring both together, it works and brings good results. Conversely, if only those who are burning with inspiration came to study today while those who feel lifeless stayed in bed, we would gain nothing. We would not have a sufficient force of egoistic desire to advance.
Our strong desire attracts the Light that Reforms. We burn with the desire to receive it and it comes. So where does the Light enter? Where is your egoistic desire that it can influence? Yet when several “dead” friends sit next to you, the Light influences them and brings them back to life. And tomorrow you will switch places, and everything will reverse.
We do not fully comprehend the unique potential of a group. Without it, spiritual advancement is impossible.
