"There are these three trainings, monks.
Which three?
The training in higher morality, the training in higher consciousness, the training in higher wisdom.
"And what, monks, is the training in higher morality? Here, monks, a monk is virtuous, etc. having accepted the training rules he trains in them. This is called, monks, the training in higher morality.
"And what, monks, is the training in higher consciousness? Here, monks, a monk, quite secluded from sensual pleasures, etc. he enters upon and dwells in the fourth meditative absorption. This is called, monks, the training in higher consciousness.
"And what, monks, is the training in higher wisdom? Here, monks, a monk understands as it really is: 'This is suffering', etc. he understands as it really is: 'This is the practice leading to the cessation of suffering.' This is called, monks, the training in higher wisdom. These, monks, are the three trainings." The ninth.
