Interesting. :) A couple of days ago I was working with a friend of mine (another reiki master) on projected healing while in astral mode. When I projected to him and started doing his healing, he had the violet flame in his heart chakra. I was told by his guides that it was a gift for him to use. When I told him about it afterwards, he did say that he called on that to do healings. When I saw it, I pulled from it's energy source to help him heal his emotional problems, feelings and things of that nature.
Thank you for confirming this for me when I read it today. He said that it did help him feel quite a bit better. :)
