Ki Energy can be activated for the purpose of healing. When you are full of positive, healthy energy then your Ki is high. When your Ki is high, life seems easier to deal with and you have a higher resistance to illness and disease.
A full Reiki treatment reopens the Chakras and re-balances the flow of the universal life force around the body. Removing blocks in energy and allowing the Life Force Energy to flow freely restores balance and allows the body and soul to heal physically, emotionally and spiritually.
Reiki speeds healing after surgery or illness and has been proven to also reduce pain. During a Reiki treatment, some people feel warmth coming from the hands of the practitioner, others feel tingling and some don't feel anything at all.
Whether you feel it or not, it is still working! :)
