I'm interested to know how biofield therapy is performed, sririam.
Robbie,
Biofield is actually a very ancient idea. In yogic science the mind is considered as connecting all living things in a common field. Similar ideas are common in other philosophical systems as well.
Surprisingly, in recent decades in Quantum Field theory it is suggested by physicists, that almost all matter and EM energy exist as fields that probably spread out like a web (magnetic and gravitational fields for example) and interact with one another. Electrons, protons quarks etc. are all now seen as fields. Please refer to my thread on 'Fields' a little down the line in this section.
Since the mind and body are interconnected and influence one another, the biofield influences the body and generates good health or ill health depending on its condition. The interacting points between the biofield and the body are called Chakras (wheels) where the biofield forms vortices. If these points can be cleaned or energized, our health (physical and mental) can be improved. This is the fundamental principle behind energy healing.
There is Pranic healing, Reiki, Faith healing, hands healing etc. all of which are variations of the same thing. These are more useful and work better in sensitive people with delicate constitutions rather than on the hardy types, because the mental (biofield) factor will be dominant as compared to the physical (body) factor.
Here are some sites that could be useful to you. You could also google and read about these matters.
