The Book of the Gradual Sayings
X. The Book of the Tens
XV: The Ariyan Way (a)
Bright Way and Dark Way
Translated from the Pali by F. L. Woodward, M.A.
 THUS have I heard:
Once the Exalted One addressed the monks, saying:
"Yes, lord," they replied, and the Exalted One said:
"Monks, I will teach you dhamma that is the bright way, likewise dhamma that is the dark way.
Do ye listen to it.
Pay attention carefully and I will speak."
"We will, sir," replied those monks to the Exalted One,
who said this:
"And what, monks, is dhamma that is the dark way?
This is called 'dhamma that is the dark way'.
And what, monks, is dhamma that is the bright way?
This is called 'dhamma that is the bright way'."
