In this Baharestan anecdote Jami builds a satirical conceit around frigid poetry (شعر سرد / خنک) treated as a literal bodily ailment. A poet complains of a knot in his heart that brings on chills and gloom; a witty physician diagnoses an unrecited bad poem as the cause and cures him by making him read it aloud, since the poem's coldness escapes once it leaves the heart. The closing verse extends the pun — such verse read over a feverish patient would turn a burning fever (تب محرق) into shivering chills (تب لرزه). The passage distills how the Persian critical vocabulary for weak verse (coldness, frigidity) is mapped onto medicine to mock lifeless poetry.
