thnx Neko13 for giving him the urls!
I've been busy these past few days and didnt get on the net & only just saw it.
you should also go to www.angelreiki.nu
and click the link for reiki plain and simple. Its a good site with a lot of info in it that you can follow more easily than some of the others.
In a nutshell: Reiki is the channeling of energy through the practioner to whatever needs to be treated in the patient. It is normally done via the 7 chakras on the body and is very useful for treating injuries.
Level 1 practioners heal on a physical level, L2 - emotional healing, L3 - spiritual
You can treat humans, animals, whatever. Reiki energy feels like warm sunshine. You will usually feel very relaxed and comfortable.
Feel free to ask any questions you want to know about reiki, I can help you with most of them as I am a Master teacher and can create new reiki practioners.
The attunement is where the Master basically connects you to source and prepares you to start channeling reiki. Each attunement will raise your personal frequency so that you can do this. You can only start channeling Reiki energy once you have been attuned.
The use of crystals and colours is more a new age thing and not strictly reiki although some crystals can help enhance treatments.
Please note that what Neko said about "cult" is not true, Reiki is not a cult. It is a way of healing. You do not have to believe in it for it to work!
