All of Israel are responsible for one another (Sanhedrin, 27b, Shavuot 39).
(Continuation of How To Stop Thinking About Myself, Part 1)…
7. If in the group everybody thinks about all the others, the group becomes a perfect system that exists in the state of Arvut (mutual guarantee) or one soul. All the friends rise above their desires and enter a unified interconnection between them, thereby becoming guarantors in bestowal to each other.
Each person detached his “point in the heart” from his egoism and connected it with the “points in the hearts” of the others. Thus, the desires remained “below,” and the connection occurs between the “points in the heart.” In such connection of mutual bestowal, there act essentially different, altruistic laws. A new world opens its doors before a person.
8. Once a person has risen above his egoism, correction of his connection with the others begins by means of the previously rejected desire. At first it happens in “bestowal for the sake of bestowal” and then in “reception for the sake of bestowal.” All relationships are carried out solely to delight the Creator. This collective spirit that is present among the friends manifests in everyone; they are now able to detect and aim their intention solely at it.
There appears a sensation of interaction neither with oneself nor with the others, but with the unified whole. The relationship with the Creator Who is being revealed in the unified whole emerges from this unity.
