11.7

「又有三成法、三修法、三覺法、三滅法、三證法。云何三成法？一者親近善友，二者耳聞法音，三法法成就。云何三修法？謂三三昧：空三昧、無想三昧、無作三昧。云何三覺法？謂三受：苦受、樂受、不苦不樂受。云何三滅法？謂三愛：欲愛、有愛、無有愛。云何三證法？謂三明：宿命智、天眼智、漏盡智。

“There are also three things to be achieved, three things to be cultivated, three things to be recognized, three things to be ceased, and three things to be realized.

“What are three things to be achieved? First is making good friends. Second is listening to the voice of Dharma. Third is accomplishing [consecutive] teachings.

“What are three things to be cultivated? They are the three samādhis: the samādhi of emptiness, the samādhi without attributes, and the samādhi without actions.

“What are three things to be recognized? They are the three feelings: painful feelings, pleasant feelings, and feelings that are neither painful or pleasant.

“What are three things to be ceased? They are three cravings: craving of desires, craving for existence, and craving to not exist.

“What are three things to be realized? They are the three insights: the knowledge of past lives, the knowledge of the heavenly eye, and the knowledge that the contaminants are ended.
