Nature can heal every wound. From the deepest emotional traumas to broken bones.
As a man made dam blocks the natural flow of a river, so do some of the inner complications that result from our wounds and injuries.
The seers who invented healing systems such as Ayurveda, Yoga, and Jin Shin Jyutsu were keenly aware of these dynamics, which is you find them focusing entirely on the removal of subtle, energetic "stuck" conditions, underpinning our more manifest maladies.
As the breaking of a dam naturally releases the river to once again flow according to its own design, so do Nature's infinite healing powers flow when these stuck conditions are dissolved.
And there is nothing these powers can't heal (according to an individual's life plan, of course.)
