There are five different brain waves: Beta, Alpha, Theta, Delta and Gamma. These brain waves of the human mind / brain are constantly in motion and producing waves in all of these frequencies. Everything that you do and everything you say is regulated by the frequency of the brain waves.
A Theta state is a very deep state of relaxation; the state used in hypnosis. The brain waves are slowed to a frequency of 4-7 cycles per second. Sages meditate for hours to reach this state in which they are able to access absolute, perfect calmness. Theta brain waves can be thought of as the subconscious; they govern the part of our mind that is layered between the conscious and the unconscious. They hold memories and sensations. They also govern your attitudes, your beliefs and your behaviours. Theta brain waves are always creative, inspirational, and characterized by very spiritual sensations.
Healing in the Theta state is not a new theory of healing. Many hypnotists have tried it and have actually worked with people in the Theta State . They bring the client and the health practitioner to a Theta state, achieving amazing results. Vianna enlisted the help of a physicist, who made her an electroencephalograph, to test brain waves on people from different healing modalities. She found that people who were Reiki practitioners utilized the high Alpha brain wave. Importantly she confirmed that the Theta Healing® technique she was using was taking practitioners, clients and students into a Theta brain wave. It is also believed that a person in this Theta state is connected to God-Consciousness. And if you call upon God / Creator in this state, you can command a healing.
