Is it better than acupuncture or are they two different approaches? And does Reiki work on your chakras' and or soul?

Although I'm a certified Reiki Master Teacher, I would say that neither is better as they are both entirely different approaches.

Accupuncturists place small needles in various pressure points in the body and are able to cure people of many ailments and allergies.

Reiki on the other hand is non-contact. The practitioner places their hands about an inch above the body and the healing energy moves through the recipients body via the hands of the practitioner. When I am doing a reiki session I work my way down over the five chakras, however, I am often guided to place my hands over other parts of the body where I feel heat and know that the healing energy is needed.

Reiki works on your mind, body and soul. So, in answer to your question .. reiki works on your chakras and your soul.
