Answer: The friends can support one another only through the Creator. We are not connected. From the moment the shattered desire to receive was revealed, we no longer have been in direct connection with each other. But the Creator enters the void between us.
Only He connects us. We will never be connected in the same way again, being adhered like drops of water that are incorporated into one drop. The Creator enters the void between us as the force of mutual bestowal and the force of receiving is also present there, the Klipa. So the intensity of the connection between us grows 620 times stronger than it was before.
After all, because both the force of the Klipa, the desire to receive, and the force of the Light have to work together so that we will connect and reach the same unity that was in Adam HaRishon (first man), when he was one soul, one vessel, without any inner cracks. Now we have to glue our pieces together. Each of them grew 620 times by its ego, but we still have to glue them together. This means that a soul, a vessel, of a totally new intensity is created.
