The realization of Reiki involves the transfer of vital energy that makes the body in energetic balance, generating a feeling of physical and mental well-being, improving mood and promoting health. During the sessions the Reikian will place his hands on the person's body in order to change the oscillation or vibration of the energies and this brings some proven benefits such as pain relief and reduction of anxiety and stress symptoms. The practice of Reiki is safe and does not have any side effects, nor is it linked to a religion, and it can be accepted by people of different origins and beliefs. It can also be applied in conjunction with other therapeutic techniques.
