Part Four Overview
This part, while it seems to have some physical aspects, definitely focuses on the endurance of the mind in particular. My focus on my goals improved while using this part. It does not erase or prevent obstacles on its own, but it seems to remove the impulse to all smaller things to pull your focus from the overall goal. It does not really address anything on an emotional aspect. If anything, it dulls emotions a bit so you can focus more, which can be a problem if one relies on emotions with their magic.
I associate this part of the 42 Letter Name with Mercury. The next part will likely address things on both a mental and emotional level, as it is credited to help with intuition and foresight.
