The Chakra Centres  
Each part of the body has a corresponding emotion, a yin and yang energy. If you know the positive and negative aspects of these areas, you can direct healing energy to that section of the body that will need healing the most. You can assist the client in understanding the underlying cause of their illness and use healing energy to bring that issue to the surface. But the wonderful thing about spiritual healing is that the Divine already knows this to be the process. So even if you don't feel comfortable explaining your perceptions, then that's fine too. Just let healing energy do what it needs to do, and if the Divine energy is coming to this person with the intent of raising issues, then that is between the client and his or her
Higher Self or Spirit or their God.
