All matter is infused with the vibrations of life force energy. This is why we can draw on the life force energy and use this energy. When you are using spiritual gifts, you are using this natural, life force energy and transferring it to be used with a spiritual gift.
For example, when you are using this energy for healing, you are guiding this natural energy (or Qi) to do a specific task. You give it an assignment and this energy is then changed to be used in the healing process. This is the spiritual gift of Command Projection, which takes the energy of the fourth chakra vibration and converts it to the projected and directed energy of healing you are guiding it to do.
