Those who have neglected the Noble Eightfold Path have neglected the noble path leading to the complete destruction of suffering. Those who have undertaken the Noble Eightfold Path have undertaken the noble path leading to the complete destruction of suffering. (Connected Discourses of the Buddha -Maggasamyutta)
What is the holy life? It is this Noble Eightfold Path; that is, right view ...right concentration. This is called the holy life.
What are the fruits of the holy life? The fruit of stream-entry, the fruit of once-returning, the fruit of non-returning, the fruit of arahantship. These are called the fruits of the holy life. (Maggasamyutta).
