We know that the mind asserts a powerful influence over the body because of the impressive power of the Placebo Effect. If unconscious attitudes have the power to make you sick or well, we might expect that a trained, focused and conscious mind might be able to do even more.
You can go to a cave in northern India and wait for an adept master of yoga teaches you what he can of his discipline….
….or you can study with Wim Hof, who offers a direct and efficient path toward conscious control over the autonomic nervous system.
Wim is famous for hiking endurance, holding his breath 6 minutes, and immersing his body in ice water for an hour at a time. Beyond the jaw-dropping stunts, he has learned to control his nerve system, turning his immune response on and off at will.
