Chapter XVI: Controlling Powers
Controlling Powers (a)
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 controlling powers.
The controlling power of faith,
the controlling power of energy,
the controlling power of mindfulness,
the controlling power of concentration.
These are the four controlling powers"
 Indriyāni. Cf. K.S. v, 168, [sic 169], 179 [sic.? 181] (Six faculties). I have kept 'faculties' for those that are physical. That of insight is added to our four. They are much the same as balāni, 'strong things' (below).
