The Discourse on Non-Decline
206.
"I will teach you, monks, seven conditions preventing decline;
listen to that.
And what, monks, are the seven conditions preventing decline?
That is to say -
the seven factors of enlightenment.
Which seven?
The enlightenment factor of mindfulness, etc.
the enlightenment factor of equanimity -
these, monks, are the seven conditions preventing decline."
