“Bhikkhus, whatever clansmen in the past rightly went forth from the household life into homelessness and made the breakthrough to things as they really are, all made the breakthrough to the Four Noble Truths as they really are. Whatever clansmen in the future will rightly go forth from the household life into homelessness and make the breakthrough to things as they really are, all will make the breakthrough to the Four Noble Truths as they really are. Whatever clansmen at present have rightly gone forth from the household life into homelessness and make the breakthrough to things as they really are, all make the breakthrough to the Four Noble Truths as they really are.

“What four? The noble truth of suffering, the noble truth of the origin of suffering, the noble truth of the cessation of suffering, the noble truth of the way leading to the cessation of suffering. Whatever clansmen made the breakthrough … will make the breakthrough … make the breakthrough to things as they really are, all make the breakthrough to these Four Noble Truths as they really are.

“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.’”
