9.23

「復有五法，謂五趣解脫：一者身不淨想，二者食不淨想，三者一切行無常想，四者一切世間不可樂想，五者死想。復有五法，謂五出要界：一者比丘於欲不樂、不動，亦不親近，但念出要，樂於遠離，親近不怠，其心調柔，出要離欲，彼所因欲起諸漏纏，亦盡捨滅而得解脫，是為欲出要。瞋恚出要、嫉妬出要、色出要、身見出要，亦復如是。

“There are another five things, which are five ways to head for liberation: First is the concept that the body is impure, second is the concept that food is impure, third is the concept that all formations are impermanent, fourth is the concept that all worlds are unpleasing, and first is the concept of death.

“There are another five things, which are five spheres of escape: [1] A monk doesn’t enjoy, isn’t moved by, and doesn’t stay near desires. He’s only mindful of escaping them, enjoys seclusion, and befriends those who aren’t indolent. His mind is flexible, leaving and parting with desire and what causes the desires that produce the web of contaminants. He also ends, abandons, and ceases them to attain liberation. This is the escape from desire. [2] The escape from anger, [3] escape from jealousy, [4] escape from form, and [5] escape from personality view are likewise.
