This healing energy of prana, like Reiki, can be quite uncomfortable for the sick. The are deep bone pains that are aching, lightning like shooting pains along the nerves and organs that are muscular like the heart can hurt in spasms and pangs.
But here are two clear routes of energy that it heals by. The guides say the first is general and the second is specific to distemper.
Apparently the homeopathy is to ease the blocks that make it hurt in the Distemper/FIP route: Bufo for the head region, Helianthus to move it past the heart, Grindelia past the gut and Nat Sulph down the spine.
If you heal from the crown, it should circle the body concentrically: top of the head to the abdomen to the forehead to the upper abdomen to the throat then the solar plexus then the heart. This is the correct cycle.
Distemper/FIP/Diabetes healing route:
It goes from the nose to the lower abdomen (diarrhoea may result for both of you!) then to the ground then from there to the heart and from there to the spine and nerves.
The nose route is specific to bone problems such as distemper (where teething trouble and bad bones is an issue).
