What is Reiki?
It is a self-contained natural healing system which works with the Physical (e.g. sickness-cancer), Mental ( e,g. thoughts like- "I am so stupid"), Emotional (e.g. "I feel angry"), and Spiritual (i.e. Being a spiritual person is synonymous with being a person whose highest priority is to be loving to yourself and others... caring about people, animals and the planet.)
The healing may occur in any of these areas or higher levels whatever helps the person. Hand positions are used in 12 or more areas with symbols called. Kunji. Reiki can be used on anything needing help.
