摩訶止觀 7.106

7.106

若修四觀破四顛倒，道心欝起生大怖畏。如為怨逐，如叛怨國，如行險道，念念周慞祇求出路。麞聞獵圍，霍驚絕走，雖遇水草何暇飲噉？志在免脫，聲聞如是。

If one cultivates the four contemplations and shatters the four inversions, the mind of the Way surges up and great terror arises. It is like being pursued by an enemy, like fleeing an enemy state, like traveling a perilous path, alarmed and hurried in every thought-moment, seeking only a way out. A roe deer hearing the hunting circle is suddenly startled and runs desperately; even if it encounters water and grass, how would it have leisure to drink and eat? Its aim is escape and release; the śrāvaka is like this.
