Reiki is simply another word for universal life force energy--the energy of all things around us and within us. Some call this life-force energy chi, Qi, Ki or Prana. Regardless of our reference, Reiki works on the principle that when energy is freely flowing within the system, the system thrives and when this energy flow is disturbed or blocked, the system becomes unwell. Impaired energy flow can manifest as physical, psychological, spiritual or other forms of unrest impeding wellbeing. Reiki is also often used as shorthand to describe a reiki treatment, which describes a gentle way of working with “life energy” to help restore balance, deep relaxation and a sense of calm.
