Many cultures believe in physically healing through magick. It isn't always possible because there must be complete faith from both the healer and the patient. That's what makes it difficult and not consistently effective.
Have you ever heard of certain locations people flock to for healing? I remember one story I heard was of Saint Genevieve. Her body never decomposed. There is a water near the area where she was somehow tied in with her life, that people have been miraculously cured of their diseases and injuries from. I remember watching it on a documentary about 15 years ago and it stuck in my mind this long.
I've always loved Saints...the enlightened magick practioners that continue to work magick to help others even after death. What's there not to like?
This is just one of many such bodies of water/locations of documented "miracles". The key to it is belief/faith. So many believe, it fuels the magick of these areas. When people are healed, it boosts belief even more, strengthening the magick. The power of the mind is strong and the power of many minds, even stronger. Water is a catalyst. Magick is energy and just as electricity will travel through water effortlessly, so too does magick. Water is also believed to be a sort of conduit between worlds, so the manifestation of magick would be more likely to occur through water as a medium.
It would be worth it to do some research and see what place of healing you may be capable of traveling to. Be sure its one with documented miracles. But if you choose to do it, you MUST have full faith. Doubt is the killer of magick and pessimism feeds illness.
