[415] What five things partake of decline (hānabhāgiyā)? The five kinds of mental barrenness (cetokhila). Friends, here a bhikkhu doubts the Teacher, is uncertain about him, is not resolved upon him, does not have confidence in him; his mind (citta) does not incline to ardor (ātappa), to application, to perseverance, to striving. Friends, when a bhikkhu doubts the Teacher, is uncertain about him, is not resolved upon him, does not have confidence in him, his mind does not incline to ardor, to application, to perseverance, to striving. One whose mind does not incline to ardor, to application, to perseverance, to striving — this is the first mental barrenness.
Furthermore, friends, a bhikkhu doubts the Dhamma, is uncertain about it, is not resolved upon it, does not have confidence in it … he doubts the Saṅgha … he doubts the training … he is angry with his companions in the holy life, displeased, with a mind assailed, become barren. Friends, when a bhikkhu is angry with his companions in the holy life, displeased, with a mind assailed, become barren, his mind does not incline to ardor, to application, to perseverance, to striving. One whose mind does not incline to ardor, to application, to perseverance, to striving — this is the fifth mental barrenness. These are the five things that partake of decline.
