From Bob and Maggie, Trance Healing Mediums:
Trance is just one of the many levels of consciousness and these can be measured scientifically using EG machines and are measured in units of Hertz. These can then be broken down into four levels:
Beta 30 – 13 hertz (panic, hyperactive, twitchy, ok)
Alpha 13 – 8 hertz (calm, quietness, light trance)
Theta 8 – 4 hertz (partial loss awareness to out of body)
Delta 4 – 0.5 hertz (guides controlling to full deep trance)
Trance Healing is an advancement of Spiritual Healing:
Spiritual Healing is where the person who is the healer acts as a channel for healing energies, from the world of Spirit, allowing this energy to flow through them to the patient. The more the healer is able to attune to the Spirit World the deeper is the healing effect. The healing energy will pass to the patient as the healer places his/her hands lightly on or over the patient's body.
With Trance Healing the medium attunes with the Spirit World. This allows their Healing Guides to come very close into the mediums aura. The deeper the level of trance, the closer the Spirit Guides are able to come into the healers aura.The medium then allows the Spirit Guides to channel this energy and use his/her arms and hands to do the healing work.
