Paṭhamasekhasutta
Vuttañhetaṁ bhagavatā vuttamarahatāti me sutaṁ:This was said by the Blessed One, said by the Arahant, so I have heard:
“Sekhassa, bhikkhave, bhikkhuno appattamānasassa anuttaraṁ yogakkhemaṁ patthayamānassa viharato ajjhattikaṁ aṅganti karitvā nāññaṁ ekaṅgampi samanupassāmi yaṁ evaṁ bahūpakāraṁ yathayidaṁ, bhikkhave, yoniso manasikāro.“Monks, with regard to internal factors, I don’t envision any other single factor like appropriate attention as doing so much for a monk in training, who has not attained the heart’s aspiration but remains intent on the unsurpassed safety from bondage. Yoniso, bhikkhave, bhikkhu manasi karonto akusalaṁ pajahati, kusalaṁ bhāvetī”ti.A monk who attends appropriately abandons what is unskillful and develops what is skillful.
Etamatthaṁ bhagavā avoca. Tatthetaṁ iti vuccati:
“Yonisomanasikāro, dhammo sekhassa bhikkhuno;Appropriate attention as a quality of a monk in training: Natthañño evaṁ bahukāro, uttamatthassa pattiyā;nothing else does so much for attaining the superlative goal. Yoniso padahaṁ bhikkhu, khayaṁ dukkhassa pāpuṇe”ti.A monk, striving appropriately, attains the ending of stress.
