The National Occupational Standards for Reiki require practitioners to have a Reiki lineage that can be traced directly back to Mikao Usui and have to have been attuned/initiated in person. You can view Alison's Lineage here
Many different styles of Reiki have since been developed and although Alison is inititiated in the Classical Style of Usui at Master/Teacher Level, she is also attuned to Egyption Seikim and is a Psychic Reiki Master.
This definition is taken from the Reiki Council Website which is the lead organisiation of Reiki in the UK and of which the UK Reiki Federation is a verifying member:
“Reiki” (ray-key) is Japanese for ‘universal life energy’, a term used to describe a system of natural healing. This healing tradition was founded by Dr Mikao Usui in the early 20th century and evolved as a result of his research, experience and dedication.
We live in a world of energy that nourishes and maintains all living things. When this energy flows uninterrupted there is balance and harmony within and around us and we experience a sense of well being. There are many variations of Reiki, but in essence Reiki works at bringing us into balance and is believed therefore to reinforce the body’s natural ability to heal itself at all levels, whether physical, mental, emotional or spiritual. It is a tradition that is open to any belief system.
Reiki is a healing process that anyone can benefit from in the normal course of their life. Research using animals and even bacteria suggests it has the ability to reverse stress-induced conditions. It should not, however, be regarded as a cure for conditions. As a natural form of healing Reiki can support and enhance other forms of treatment.
The method of receiving a Reiki treatment from a practitioner is simple. The recipient remains clothed and lies on a couch or sits on a chair and relaxes. The practitioner gently places their hands non-intrusively, on or near the body. There is no massage or manipulation and the whole person is treated rather than specific symptoms. It is also possible to receive Reiki at a distance.
Reiki practitioners are not trained in diagnosis and will not offer any diagnosis or prognosis. If people are concerned about their symptoms they should see a doctor. Clients may or may not feel sensations during a Reiki treatment. Benefits reported by clients/patients include deep relaxation promoting a calm, peaceful sense of well being on all levels.
