[1029] "Bhikkhus, just as, so long as the peak of a peaked house has not been raised, there is as yet no placing of the rafters, there is as yet no steadying of the rafters; but when, bhikkhus, the peak of the peaked house has been raised, then there is the placing of the rafters, then there is the steadying of the rafters — even so, bhikkhus, so long as noble knowledge (ariyañāṇa) has not arisen in a noble disciple, there is as yet no placing of the four faculties (indriya), there is as yet no steadying of the four faculties. But when, bhikkhus, noble knowledge has arisen in a noble disciple, then … there is the steadying of the four faculties. Of which four? Of the faculty of faith (saddhindriya), the faculty of energy (vīriyindriya), the faculty of mindfulness (satindriya), and the faculty of concentration (samādhindriya)."
