Answer: Circulation has absolutely nothing to do with spiritual connection between us. It is a burden we have accepted as our duty so as to serve the world on the corporeal level. Obviously, it is desirable that dissemination were done solely by our people since they can infuse it with the spiritual spark, but in principle, we can recruit outsiders for it as well.
As to spirituality, it is defined as our unity above the level of egoism or our climbing the spiritual degrees by acting above reason. There is no other possibility. This work is not related to dissemination; it is personal and available to everyone, even if the person lives in Alaska in complete isolation.
True circulation is spreading one’s desire for connection and love in the entire network of connections between the souls.
