Answer: There are no corporeal problems. The corporeal world doesn’t exist separately from the spiritual world. Everything belongs to the spiritual world. The corporeal form that we feel now only seems corporeal since we perceive it without the right intention; this should be established by our own efforts. We were simply born this way with shattered desires.
The feeling in the shattered vessel, without any independent intention and only according to the vessel’s development plan, is called the corporeal world. This means that corporeality is what I feel without making any efforts. In order to feel spirituality, I have to focus myself in a certain manner, and only then will I be able to feel it. These actions are called corrections.
Our world is actually the base of the whole system of the spiritual world. The system of the upper worlds is revealed in the form of additional connections between all the elements of reality. This network is called the upper worlds.
