What religion doesn't believe in god but believes in auras and reiki?

The various beliefs you are speaking about are not orthodox "religions" but rather systems of mental and metaphysical concentration and relaxation techniques. Their purpose is to allow the individual to discover his or her own enlightenment by following the path of their choice. People who accept such beliefs are commonly and collectively known as "spiritualists", although the term is far to broad and does nothing to describe the true nature of any one of the many encompassed disciplines. Many "born again" spiritualists also believe in the god of the christian faith. In some circles, spiritualism in its many itterations has become some kind of owners club, whereby the individual is encouraged to bastardise power of thought through meditation to further his own wants and needs. Such behaviour is a perversion of discipline but is tollerated because tollerance and patience are what meditation teaches. It is important to add that all religions share a belief in God. Most spiritualists do the same, or believe in a higher spiritual being, but may not belong to a particular faith. Reiki is not religious, but nevertheless used by people of all faiths around the world.
