Reiki Attunements are said to connect one to the Universal energy and are carried out by Reiki Masters on their Reiki students during Reiki teaching. They are a vital part of Reiki, as, by connecting you to Universal energy, they allow you to ‘channel’ energy for healing, rather than use your own life force energy (also known as Chi). This makes Reiki unique in its way and different from other healing systems that only use healer’s Chi energy for healing.
Reiki Attunements are believed to be followed by 21-day cleansing process, during which physical, emotional, mental and spiritual healing is said to take place. The cleansing process is considered to occur due to Attunement to higher frequency energies during Reiki Attunement. Higher energies tend to heal one on physical, emotional, mental and spiritual levels, getting rid of negative energies.
