Baal HaSualm, “The Arvut (Mutual Guarantee)”: Therefore, the Tana described the Arvut as two people on a boat, when one of them began to drill a hole in the boat. His friend asked, “Why are you drilling?” He replied, “What business is it of yours? I am drilling under me, not under you.” So he replied, “Fool! We will both drown together!”
From this we learn that since those rebels wallow in self-love, by their actions they build an iron wall that prevents the observers of the Torah from even beginning to fully keep the Torah and Mitzvot in the measure of “Love thy friend as thyself,” which is the ladder for reaching Dvekut (adhesion) with Him. And how right were the words of the proverb that said, “Fool, we shall both drown together!”
This is a very clear example: No matter where the hole is, in any case, I eventually drown and as a result everyone dies. This is why we should worry about all the participants, and this concern should first be revealed internally, inside me, when I worry about my own desires, and also outwards when I worry about the group and the world.
A person is a small world. Eventually my inner structure connects with the structure of the group and the structure of the whole world. So it turns out that if I could keep the right, accurate, basic form of my vessels, the corrected and the uncorrected ones, I could keep the external vessels of the group and of the whole world. This is called “judges himself and the whole world to the scale of merit.”
We can bring the example of a Matryoshka (a set of nesting dolls): I am inside, then there is the group, and then the whole world. And all of this is only in my imagination—my ego is divided into “layers” from the internal layer to the external layer. Actually, however, it is about one structure, one system. Therefore, I am responsible for everyone. If I carefully guard myself, I guard the whole world by that.
Thus the correction is carried out internally. Of course I should also worry about the external part, but the real work is done inside me. Therefore by growing stronger internally, we radiate the power upon our groups and upon the whole world.
