i don't claim to be an expert but i have studied many religions and from my understanding there are several who practice chakra related healing. some groups call it different things but they are talking about the same concept. some new age followers practice it as well as reiki healers. buddhists and hindus have beliefs associated with chakra's. buddhist influenced cultures like China, Japan, etc. use practices like moxibustion and accupuntcure which relate to proper flow of chi (ki, qi, various names depending on the group) by releasing blockages in chakras.

hope some of this helps answer your questions... while there is a lot of good info online to research, always make sure you have a reliable source. while i do sometimes enjoy wikipedia it is a HORRIBLE source as far as reliability goes.
