Brennan Healing Science was created by Dr. Barbara Ann Brennan, a former NASA physicist. In BHS, universal energy is channelled through the crown chakra and also drawn up from the earth to make it available to the client through the palm chakras. Thus, a wider spectrum (frequency) of energy is made available to the client than is available in Reiki. The energy is made available by the laying the hands (called a chelation) on positions (usually on the front of the body) that closely parallel the endocrine system, the chakras and the major articulations as well as any other part of the body that is in need of healing.
BBSH practitioners learn techniques to work with the seven levels of the field, to dissolve the energy blocks in the field (aura), restructure lines of light which are the template for the physical body, and repair the energy field of organs and chakras so that they can metabolize universal energy to nourish the human body and return it to a healthy functionality. Many other techniques are also available to the BHS practitioner, including past life healing, relational cords and spiritual surgery assisted by spirit guides.
