Answer: It is in order to develop the soul, because only when we are in this world can we develop and fulfill our soul and reach a state of wholeness and eternity. This world is very important. It is only necessary to know how to realize it correctly, because only from this world and only within it can we attain the highest spiritual goal.
If we imagine that our world is nothing, that we are like insects crawling on the surface of a small ball that is going to be lost in space, this is not right.
If we begin to create a connection with the upper force, feeling our connection with it, then we begin to see the entire system of nature correctly and feel that we are in the center of creation. We understand how it is up to us to act and what to do.
This is what we have come for, and the emptiness that was created around us helps us with this and pushes us forward.
