The Buddha provides a detailed and rigorous method for examining a Teacher. By discerning the teacher’s mental qualities, through prolonged observation, questioning, and learning directly, one gradually realizes a certain aspect of the teaching and builds unshakeable confidence in both the teacher and the teachings.

The Buddha recounts how he attained full awakening by examining the principle of dependent co-arising. He likens this realization to a man discovering an ancient, forgotten city.

The Noble Eightfold Path is the path and the way of practice for the realization of enlightenment.

Ven. Sāriputta answers the question of what is difficult to do in the teaching and discipline, and what is difficult for one who has gone forth.
