[532] "Bhikkhus, there are these three urgent duties of a farmer householder. What three? Here, bhikkhus, a farmer householder quickly gets his field well plowed and well harrowed; having quickly gotten his field well plowed and well harrowed, he quickly plants the seeds; having quickly planted the seeds, he quickly lets the water in and lets it out. These, bhikkhus, are the three urgent duties of a farmer householder. Yet, bhikkhus, that farmer householder has no such supernormal power (iddhi) or might that he could command: 'Let my crops spring up this very day, let them form ears of grain tomorrow, let them ripen the day after tomorrow.' Rather, bhikkhus, there comes a time when, with the change of season, that farmer householder's crops spring up, form ears of grain, and ripen.
"Even so, bhikkhus, there are these three urgent duties of a bhikkhu. What three? The undertaking of the training in higher morality (adhisīla-sikkhā), the undertaking of the training in higher mentality (adhicitta-sikkhā), and the undertaking of the training in higher wisdom (adhipaññā-sikkhā). These, bhikkhus, are the three urgent duties of a bhikkhu. Yet, bhikkhus, that bhikkhu has no such supernormal power or might that he could command: 'Let my mind (citta) be liberated from the taints (āsava) through non-clinging this very day, or tomorrow, or the day after.' Rather, bhikkhus, there comes a time when that bhikkhu's mind is liberated from the taints through non-clinging.
"Therefore, bhikkhus, you should train yourselves thus: 'Keen shall be our zeal (chanda) in undertaking the training in higher morality; keen shall be our zeal in undertaking the training in higher mentality; keen shall be our zeal in undertaking the training in higher wisdom.' Thus, bhikkhus, should you train yourselves."
