Reiki
Although spiritual in nature, Reiki is not a religion. It has no dogma, and there is nothing you must believe in order to learn and use Reiki. Reiki comes from God, but will work whether you believe in it or not. Its use is not dependent on ones intellectual capacity or spiritual development, and thousands of people of all ages and backgrounds have been attuned to Reiki. Intention increases its effectiveness, but it can never be done incorrectly.
