“Suppose that he who does the deed and he who experiences the result are one and the same. Then for one who has existed since the beginning, suffering is made by oneself. In speaking like this, one implies this is eternal. Suppose that he who does the deed is one, and he who experiences the result is another. Then for one stricken by feeling, suffering is made by another. In speaking like this, one implies this is annihilated. Avoiding these two extremes, the Realized One teaches by the middle way: ‘Ignorance is a requirement for choices. Choices are a requirement for consciousness. … That is how this entire mass of suffering originates. When ignorance fades away and ceases with no residue left behind, choices cease. When choices cease, consciousness ceases. … That is how this entire mass of suffering ceases.’”
When this was said, Kassapa said to the Buddha, “Excellent, sir! Excellent! As if he were righting the overturned, or revealing the hidden, or pointing out the path to the lost, or lighting a lamp in the dark so people with clear eyes can see what’s there, the Buddha has made the teaching clear in many ways. I go for refuge to the Buddha, to the teaching, and to the mendicant Saṅgha. Sir, may I receive the going forth, the ordination in the Buddha’s presence?”
“Kassapa, if someone formerly ordained in another sect wishes to take the going forth, the ordination in this teaching and training, they must spend four months on probation. When four months have passed, if the mendicants are satisfied, they’ll give the going forth, the ordination into monkhood. However, I have recognized individual differences.”
