Monks, I do not say that final knowledge (wisdom) is achieved all at once. On the contrary, final knowledge is achieved by gradual training, by gradual practice, by gradual progress.

And how does there come to be gradual training, gradual practice, gradual progress?

Here;

One who has confidence in a Teacher visits him;

When he visits him, he pays respect to him;

When he pays respect to him, he gives ear;

One who gives ear, hears The Teachings;

Having heard The Teachings, he memorizes them;

He examines the meaning of The Teachings he has memorized;

When he examines their meaning, he gains a reflective understanding of those Teachings;
