“Bhikkhus, suppose that a man would place on Sineru, the king of mountains, seven grains of gravel the size of mung beans. What do you think, bhikkhus, which is more: the seven grains of gravel the size of mung beans that have been placed there or Sineru, the king of mountains?”
“Venerable sir, Sineru, the king of mountains, is more. The seven grains of gravel the size of mung beans are trifling. Compared to Sineru, the king of mountains, the seven grains of gravel the size of mung beans are not calculable, do not bear comparison, do not amount even to a fraction.” sn.v.458
“So too, bhikkhus, for a noble disciple, a person accomplished in view who has made the breakthrough, the suffering that has been utterly destroyed and eliminated is more, while that which remains is trifling. Compared to the former mass of suffering that has been destroyed and eliminated, the latter is not calculable, does not bear comparison, does not amount even to a fraction, as there is a maximum of seven more lives. He is one who understands as it really is: ‘This is suffering’ … ‘This is the way leading to the cessation of suffering.’
“Therefore, bhikkhus, an exertion should be made to understand: ‘This is suffering.’… An exertion should be made to understand: ‘This is the way leading to the cessation of suffering.’”
