Delurking, as I noticed Gee's post on the last thread about her sick relative.
I am not a witch (thought very respectful of, and interested in the craft) but I am a spiritual healer, and I would be happy to send absent healing to your relative Gee, if you would like. If so, just send me a PM with their first name.
In terms of how you can help sending healing energies, in Spiritualist circles we usually advise people to pray/ask for healing for the person, while visualising them as happy and well, surrounded by protective light (most people use white light, but others use gold or sometimes violet, you may get a feel for what feels right for that person, or you may see it change as you carry out the visualisation/ prayer/request).
The exception would be where they are known to be about to pass over, when you could instead visualise a peaceful passing, again with the protective light, and ask that they be met and helped to pass over.
Hope it was ok to say this on the thread, though it's not specifically a witchcraft practice. Hopefully it doesn't clash with the tenets of witchcraft, but please ignore if so.
