Joy

Joy causes qi to slacken. It includes two aspects, namely, the relaxation of sentimental strain, and dispersion of the heart-qi. Normally, joy can relax mental strain and make the nutrient-qi and defense-qi go smoothly, bringing forth a happy mood. But over joy can disperse the heart-qi, and make the mental vitality go out of its lodging, which produces a failure of concentrating attention, and in critical cases, mental disarrangement.

Qi

Sorrow causes qi to disperse. It means that great sorrow leads to suppression of the lung-qi, despondency, and consumption of the lung-qi.

It refers to the fact that great fear causes the kidney-qi to become unfixed and to go downwards, which clinically produces urinary and fecal incontinence, or produces impairment of the essence with symptoms such as sore, flaccid, or cold bones, and seminal emissions, etc.
