Question: If we exist within an ocean of Light, then why must our physical body tolerate this life? Is it all so we will be attracted to the upper world?
Answer: Of course, we see the examples in our lives, how we pressure children in their education. We don’t let them live quietly, having fun and enjoying easy games. We compel them to learn, we determine rigid frameworks for them, and so on.
Similarly, we must pressure our body so that, with its help and specifically thanks to its resistance, we achieve the development of the soul.
