What is the Relationship between Emotion and Human Qi?

Wherever there is emotional disharmony, there too will be blockage of qi caused by unresolved emotion. Qi blockage - the chief causes of diseases - is often brought on by one’s obsession of joy, anger, worry, anxiety & sorrow, fear & fright as a result of one’s unconscious attachment to mundane concerns such as gain & loss, pleasure & displeasure, praise & abuse, fame & disrepute, whereas supramundane attitudes such as compassion, loving-kindness, altruistic intent & equanimity are the time proven counter-measure to dissolve qi stagnation. Prompted by pride & ignorance, the mind may attempt to suppress unresolved emotion by putting on an artificial performance of indifference, defiance, or other exaggerated gestures, but it cannot prevent the karmic effect of unresolved emotion from materialising of its own accord. For instance: unresolved anger will damage the liver, the gall bladder, and cause brain haemorrhage, vomiting, and other digestive ailments. Fixation of joy will cause erratic palpitation, damage the heart, disperse qi too rapidly and effect a scattering of shen. With sorrow, qi will condense, over-heat the body, leaving the constitution sluggish and pale in appearance. With worry, qi will congest, cause diarrhoea, ulcers, indigestion, constipation as well as impairment to perception. With fear, qi will implode inward, create qi seizure, injure the kidney, the heart, the bladder, and destabilise the entire autonomous nervous system.
