How to Tell If You Are Connected
Baal HaSulam explains in the article "Arvut" that no one can attain the goal without help from one's friends because otherwise a person won't have the fuel, the "spirit of life." A person on the spiritual path must arm himself with a great desire after revealing the breaking between us because the force of hatred between us lays bare the evil inclination. Even The Zohar talks about how the friends in Rabbi Shimon's group revealed hatred, and only after that did they reach love, level by level, by means of the Light they evoked through mutual study.
The goal is also something we discover inside our interconnection. By gradually restoring the connection between us with the help of the Light, we reveal 125 levels until reaching unity with the Creator. Thus, we attain the Creator Himself, the force of the Light that Reforms. If, however, we don't base everything on the revelation of the place of the breakage and its correction, then our actions will bear no connection to spirituality.
Indeed, we have just one contact with the spiritual world, and that is the place of the breakage of the connection between us. It is written, "I created the evil inclination." This is what we have to find and reveal. That is why our entire work is devoted to discerning the quality of connection between the friends on the path to revealing the Creator: me, the friends, and the Creator (or Israel, the Torah, and the Creator).
We are looking for a connection between us in which the Creator is concealed. This is the key that opens the door to Him. By correcting our attitude to our interconnection, we find the quality of bestowal and love, and that is how we reveal the Creator. This is the only way a friend can help a friend. This constitutes our only free action. All other acts are compulsory, puppet-like. We shouldn't demand anything from each other besides the desire to help.
