Answer: Psychiatric disorders will disappear very quickly if we become closer to one another. They appear only because we are separated from each other.
When we begin to connect again, or at least aspire to our common united state, then the Light will begin to cleanse us from within—all of us together—and we will again complement each other in a single harmonic system, and once again become a correctly functioning single organism.
Then all problems will disappear. After all, all diseases appear because we are separated, like a dismembered body.
