Having a great spirit means mind-practicing, requiring Buddhist disciples compassion, humanity and ego-less as well as continually setting yourself from the bondage of your psychology confusion. Modern science has very profound elaboration of psychology’s influence on human health. Regulating physical health by psychological adjustment has become an important treatment.
In fact, Buddhism has very rich theory and practice experiences in the psychological treatment. To a certain degree, 12 classics of the Buddhist Tripitaka are the very psychotherapy to treat a mountain of cares for sentient beings. The Buddhist history of more than two thousand years, to some extent, is also a history to treat psychological illness. (From Shaolin Temple Encyclopedia)
