an.2.11 Aṅguttara Nikāya (Numbered Discourses)

The Chapter on Disciplinary Issues

11
“There are, mendicants, these two powers.
What two?
The power of reflection and the power of development.
And what, mendicants, is the power of reflection?
It’s when someone reflects:
‘Bad conduct of body, speech, or mind has a bad, painful result in both this life and the next.’
Reflecting like this, they give up bad conduct by way of body, speech, and mind, and develop good conduct by way of body, speech, and mind, keeping themselves pure.
This is called the power of reflection.
And what, mendicants, is the power of development?
In this context, the power of development is the power of the trainees.
For when you rely on the power of a trainee, you give up greed, hate, and delusion.
Then you don’t do anything unskillful, or practice anything bad.
This is called the power of development.
These are the two powers.”
