"Yes, lord," the monks responded.

The Blessed One said: "It's because of not understanding and not penetrating four things that we have wandered & transmigrated on such a long, long time, you & I. Which four?

"It's because of not understanding and not penetrating noble virtue that we have wandered & transmigrated on such a long, long time, you & I.

"It's because of not understanding and not penetrating noble concentration that we have wandered & transmigrated on such a long, long time, you & I.

"It's because of not understanding and not penetrating noble discernment that we have wandered & transmigrated on such a long, long time, you & I.

"It's because of not understanding and not penetrating noble release that we have wandered & transmigrated on such a long, long time, you & I.

"But when noble virtue is understood & penetrated, when noble concentration... noble discernment... noble release is understood & penetrated, then craving for becoming is destroyed, the guide to becoming (craving & attachment) is ended, there is now no further becoming."

That is what the Blessed One said. When the One Well-gone had said that, he -- the Teacher -- said further:

Unexcelled virtue, concentration,
    discernment, & release:
have been understood by Gotama of glorious stature.
Having known them directly,
he taught the Dhamma to the monks --
    the Awakened One
    the Teacher who has put an end to suffering & stress,
    the One with vision
        totally unbound.
