The literal translation of Reiki is universal energy. It's an ancient system of healing that uses the chakras and balances the human energy field. Reiki is being studied extensively now. Studies show that Reiki invokes the relaxation response, so its healing power is in its ability to soothe anxiety and emotional distress. Reiki used to be a sort of sideline method, but it's pretty much in the mainstream now, as many hospitals in the United States have Reiki programs for their patients now. Reiki helps improve the quality of life for patients with chronic disease.
When a practitioner becomes attuned to Reiki, the ability to sense and transmit universal energy and transmit this energy to the human energy field is greatly enhanced. When a practitioner isn;t using her own energy during a Reiki session, rather, she's the conduit for channeling universal energy to others or to the self. Reiki balances the different levels of energetic fields of the body, including the chakras, the meridians, and the aura. Reiki is a method of safe, light touch and is done with the client fully clothed. So, Reiki is appropriate for families to learn and use among each other.
You can learn Reiki from a Reiki Master. There are three levels of certification in Reiki training: Reki Level One, Two and Three. In Reiki Level One, you are initiated into the energy of Reiki. You learn to practice self-Reiki and can work with your family. In Reiki Level Two, you're again attuned to the Reiki energy, and learn techniques for emotional and distance healing. In many teaching traditions, Reiki Level Three is the Master, or teacher level. Some traditions don't attune for teaching at Level Three, but require training beyond level three in order to qualify as a Reiki teacher.
If you are looking for a Reiki practitioner, it is best to see if you can get a personal referral to a practitioner from some one you know. Make sure the person has proper training and certifications to practice Reiki.
Check out his or her business reputation, ask for some references and where he or she has worked before going to their place of business.
Remember, Reiki is not a substitute for conventional medical care. It invokes the relaxation response and is used for relaxation and comfort. Reiki is a complementary technique to be used as an addition to conventional medical care. Reiki practitioners are not qualified to diagnose or treat medical or psychological conditions, and refrain from practicing outside the scope of their competence.
