[364] "And what, carpenter (thapati), are unwholesome thoughts (akusalā saṅkappā)? The thought of sensuality (kāmasaṅkappa), the thought of ill will (byāpādasaṅkappa), the thought of cruelty (vihiṃsāsaṅkappa) — these, carpenter, are called unwholesome thoughts. And these unwholesome thoughts, carpenter, have what as their origination (samuṭṭhāna)? Their origination too has been stated: it should be said that they originate from perception (saññā). What perception? For perception too is manifold, of many kinds, of diverse aspects: whatever perception of sensuality, perception of ill will, perception of cruelty there is — originating from this are unwholesome thoughts. And where, carpenter, do these unwholesome thoughts cease without remainder? Their cessation too has been stated. Here, carpenter, a bhikkhu, quite secluded from sensual pleasures, secluded from unwholesome states, enters and dwells in the first jhāna, which is accompanied by thought (vitakka) and examination (vicāra), with rapture and pleasure born of seclusion: it is here that these unwholesome thoughts cease without remainder. And practicing in what way, carpenter, is one practicing for the cessation of unwholesome thoughts? Here, carpenter, a bhikkhu generates desire (chanda), strives, arouses energy, exerts the mind, and endeavors for the non-arising of evil, unwholesome states that have not yet arisen; … for the abandoning of evil, unwholesome states that have arisen; … for the arising of wholesome states that have not yet arisen; … he generates desire, strives, arouses energy, exerts the mind, and endeavors for the stability, non-loss, increase, abundance, development, and fulfillment of wholesome states that have arisen. Practicing thus indeed, carpenter, one is practicing for the cessation of unwholesome thoughts."
