《黄帝内经·素问·脉解》
所谓恐惧不安好像被人捉捕一样，是因为秋天阴气始生，万物尚未尽衰，人体应之，阴气少，阳气入，阴阳交争，循经入肾，故恐惧如人将捕之。
所谓恐如人将捕之者，秋气万物未有毕去，阴气少，阳气入，阴阳相薄，故恐也。
The so-called "fear and anxiety as if being arrested" is because the Yin Qi in autumn has just begun to grow, and all things have not yet completely declined. The human body responds to it, the Yin Qi is less, the Yang Qi enters, and the Yin and Yang struggle. The meridians enter the kidneys, so they are afraid of being caught.
