Question: Is it possible to cross the Machsom without the knowledge of diagrams and the general system of the Universe?
Answer: Yes, it is if your work with friends is directed at true unity. However, you still need to study something to attract the Upper Light to yourself. You should work together with the group, virtually or physically, and study the material, which describes how we are connected.
By assembling a Lego set, a child builds his future states, that is, he creates something. We, too, need to create something, and at the same time we need to attract the force that will pull us towards the next level.
That is why by trying to unite in the group through studies, we attract the upper Light that unites us, and we begin to understand this scheme namely from connecting. We could not know it, but we should study it together in the group; otherwise, the upper Light will not be manifested. It manifests from those forms in which it exists.
