[531] Bhikkhus, suppose there were a bronze goblet of a beverage possessed of good color, possessed of good aroma, possessed of good flavor, but it was mixed with poison. Then a man would come along who wanted to live, who did not want to die, who desired happiness and recoiled from suffering (dukkha). They would say to him: 'Good man, this bronze goblet of a beverage is possessed of good color, possessed of good aroma, possessed of good flavor, but it is mixed with poison. If you wish, drink it. As you drink it, indeed, it will please you with its color, with its aroma, and with its flavor; but having drunk it, you will come to death or to deadly suffering.' He, without reflecting, would drink it and would not relinquish it. As he drank it, indeed, it would please him with its color, with its aroma, and with its flavor; but having drunk it, he would come to death or to deadly suffering. Just so, bhikkhus, I say this undertaking of practices (dhammasamādāna) is comparable to that — namely, the undertaking of practices that is pleasant in the present but ripens in future suffering.
