[275] Bhikkhus, there are these five kinds of mental barrenness (cetokhila). What five? Here, bhikkhus, a bhikkhu doubts the Teacher, is uncertain about him, is undecided about him, and is not confident in him. Bhikkhus, when a bhikkhu doubts the Teacher, is uncertain about him, is undecided about him, and is not confident in him, his mind (citta) does not incline to ardor, to application, to persistence, to striving. One whose mind does not incline to ardor, to application, to persistence, to striving — this is the first mental barrenness.
Again, bhikkhus, a bhikkhu doubts the Dhamma … doubts the Saṅgha … doubts the training … is angry with his fellows in the holy life, displeased, with a mind struck by resentment, become barren. Bhikkhus, when a bhikkhu is angry with his fellows in the holy life, displeased, with a mind struck by resentment, become barren, his mind does not incline to ardor, to application, to persistence, to striving. One whose mind does not incline to ardor, to application, to persistence, to striving — this is the fifth mental barrenness.
Bhikkhus, for the abandoning of these five kinds of mental barrenness, these four establishments of mindfulness (satipaṭṭhāna) should be developed.
