摩訶止觀 8.79

次、用觀不調偏僻成病者：初託胎時以思心起感召其母，母即思五：色、聲、香、味、觸等。一毫氣動為水，水為血，血為肉，肉成五根、五藏。今坐禪人思觀多，損五藏成病。若緣色多，動肝；緣聲多，動腎；緣香多，動肺；緣味多，動心；緣觸多，動脾。

Next, illnesses arising from maladjustment and one-sidedness in using contemplation: when first entering the womb, thought arises to attract the mother, and the mother then thinks of the five: forms, sounds, scents, tastes, and tangible objects. With the movement of a single hair's breath, it becomes water; water becomes blood; blood becomes flesh; flesh forms the five sense faculties and the five viscera. Now, when a meditator has excessive thinking and contemplation, it damages the five viscera and causes illness. If one attends excessively to forms, it stirs the liver; if one attends excessively to sounds, it stirs the kidneys; if one attends excessively to scents, it stirs the lungs; if one attends excessively to tastes, it stirs the heart; if one attends excessively to tangibles, it stirs the spleen.
