(S.ii.133)
74. Thus have I heard — At one time the Blessed One was dwelling at Sāvatthi, in Prince Jeta’s grove, in the monastery of Anāthapiṇḍika. Then the Blessed One picked up a small amount of dust on the tip of his fingernail and said to the monks: “What do you think, monks, which is greater? This small amount of dust on my fingernail, or the great earth?”
“Venerable sir, the great earth is far greater. The small amount of dust on the Blessed One’s fingernail is insignificant. The small amount of dust on the Blessed One’s fingernail is not even a hundredth, a thousandth, or even a hundred thousandth the amount of the great earth.”
“Even so, monks, a noble disciple endowed with right-view, an individual who has gained realisation, the suffering that is totally destroyed and exhausted is far greater; while that remaining is insignificant. Not even a hundredth part, or a thousandth part, or a hundred thousandth part of the former mass of suffering that has been totally destroyed and exhausted remains in a maximum of seven lifetimes. Thus, monks, realisation of the Dhamma is of such great benefit, that is the great benefit of gaining the eye of the Dhamma (Dhammacakkhu).” (S.ii.133)

“Even so, monks, few are those reborn again as human beings, those reborn elsewhere are far more numerous.¹ Therefore, monks, you should train yourselves: ‘I will dwell heedfully.’ Thus, monks, you should train yourselves.” (S.ii.263)
