Reiki: The Body - Mind Connection
The idea that all life is somehow simply various manifestations of a great life force can be found in religious and philosophical texts from all ages and cultures. Psychologist Sigmund Freud's protégée, Carl Jung wrote of a "collective unconscious" as did Boris Pasternak (famous Russian philosopher and author of Dr. Zhivago), and this tract from a Budhist text is another example:
Feathered birds and fishes finned
And clouds and rain and calm and wind
And sun and moon and stars declare
All life is one life everywhere.
It is now un-controversial when scientists from various disciplines claim that every thing vibrates and despite appearances to the contrary, is inter-connected by some as yet incomprehensible force and so, to some degree, everything has an effect on everything else.
Since this "every thing" must include thoughts, and thoughts are an emerging quality of the brain, and the brain is part of the body/person - (can you see where this is leading) - it stands to reason that modern medicine too, is looking again at Complementary therapies and spiritual/natural healing to see how it reconciles with this developing understanding.
