Regarding what was said that suppression [of urges] is a cause of wasting, we shall explain that in detail: when a person, being in the presence of a king, or in the presence of a master, or at the feet of a teacher, or having entered a gambling assembly or another assembly of virtuous persons, or among women, or traveling by uneven vehicles, out of fear, engagement, shame, or aversion, suppresses the oncoming urges of flatus, urine, and feces, then from that suppression vāyu undergoes provocation; being provoked, stirring up pitta and phlegm, it moves upward, downward, and obliquely; then, entering specific bodily parts in portions as described before, it produces colic, breaks or dries up the feces, causes extreme pain in the flanks, crushes the shoulders, parches the throat and chest, afflicts the head, and produces cough, dyspnoea, fever, hoarseness of voice, and coryza; then, overwhelmed by these emaciating complications, he slowly, slowly wastes away.
