Chapter XVI: Controlling Powers
(Controlling) Powers (b)
Translated from the Pali by F. L. Woodward, M.A.
 Thus have I heard:
On a certain occasion the Exalted One was staying near Sāvatthī.
Then the Exalted One addressed the monks, saying:
"Yes, lord," they replied, and the Exalted One said:
"Monks, there are these four powers.
The power of faith, of energy, of mindfulness, of concentration.'.
These are the four controlling powers"
 Cf. K.S. v, 223.
