The Long Āgama Sūtra 9.20

9.20

「復有四法，謂四淨：戒淨、心淨、見淨、度疑淨。復有四法，謂四知：可受知受、可行知行、可樂知樂、可捨知捨。復有四法，謂四威儀：可行知行、可住知住、可坐知坐、可臥知臥。復有四法，謂四思惟：少思惟、廣思惟、無量思惟、無所有思惟。復有四法，謂四記論：決定記論，分別記論、詰問記論、止住記論。復有四法，謂佛四不護法；如來身行清淨，無有闕漏，可自防護；口行清淨、意行清淨、命行清淨，亦復如是。是為如來所說正法，當共撰集，以防諍訟，使梵行久立，多所饒益，天、人獲安。

“There are another four things, which are four purities: Purity of precepts, purity of mind, purity of views, and purity of going beyond doubt.

“There are another four things, which are four recognitions: Recognizing what’s acceptable and accepting it, recognizing what’s practicable and practicing it, recognizing what’s enjoyable and enjoying it, and recognizing what’s rejectable and rejecting it.

“There are another four things, which are four postures: Recognizing what’s walkable and walking, recognizing where one can stand and standing, recognizing what can be sat on and sitting, and recognizing what can be laid upon and lying down.

“There are another four things, which are four contemplations: Contemplation of a little, contemplation of what’s broad, contemplation of what’s measureless, and contemplation of nothingness.

“There are another four things, which are four explanations: Definite explanation, analytical explanation, explanation by questioning, and explanation by setting it aside.

“There are another four things, which are four things the Buddha doesn’t guard against: [1] The Tathāgata’s physical conduct is pure and lacking any contamination he could guard himself against. [2] His verbal conduct is pure, [3] mental conduct is pure, and [4] his livelihood is pure in the same way.

“Monks, these are the correct teachings taught by the Tathāgata that we ought to compile together to safeguard them from dispute, establish the religious life for a long time, and benefit many people so that gods and people will obtain peace.
