[344] Bhikkhus, suppose the crop (kiṭṭha) had ripened, and the watchman of the crop were negligent, and a crop-eating ox, descending into that crop, were to become intoxicated to its heart's content and become negligent. In just the same way, bhikkhus, the uninstructed worldling (puthujjana), acting without restraint over the six bases of contact (phassāyatana), becomes intoxicated to his heart's content and becomes negligent among the five cords of sensual pleasure (kāmaguṇa).
Bhikkhus, suppose the crop had ripened, and the watchman of the crop were vigilant, and a crop-eating ox were to descend into that crop. The watchman of the crop would seize it, taking a firm hold of it by the muzzle; having taken a firm hold of it by the muzzle, he would restrain it, gripping it firmly above the forehead; having gripped it firmly above the forehead, he would beat it, thrashing it soundly with a stick; having thrashed it soundly with a stick, he would let it go. For a second time, bhikkhus … For a third time, bhikkhus, the crop-eating ox might descend into that crop. The watchman of the crop would seize it, taking a firm hold of it by the muzzle; having taken a firm hold of it by the muzzle, he would restrain it, gripping it firmly above the forehead; having gripped it firmly above the forehead, he would beat it, thrashing it soundly with a stick; having thrashed it soundly with a stick, he would let it go. Thus, bhikkhus, that crop-eating ox, whether gone to the village or gone to the forest, whether given to much standing or given to much sitting, would not descend into that crop again, recollecting that former contact with the stick. In just the same way, bhikkhus, when a bhikkhu's mind (citta) has been subdued, well subdued, with regard to the six bases of contact, it settles internally, becomes composed, becomes unified, and becomes concentrated (samādhi).
