If you have learned or read some other healing teachings or concepts, you will find that this is a common concept to most healers when it comes to energy healing in general. Of course, some healers will also use their internal qi on top of the Universal qi. When I use Reiki or Quantum Touch on clients, I also tap into the Universal qi to allow energy flow through me to the subjects/clients.
By allowing the Universal qi to flow through my body during a healing session as a practitioner, I am also allowing the qi to cleanse and energize (or re-balance) in my body as well. Therefore, I am helping myself while I am helping others. That is the main reason for my improved physical and emotional health over the last few years.
