Non-decline

“Mendicants, I will teach you seven principles that guard against decline.
Listen …
And what are the seven principles that guard against decline?

They are the seven awakening factors.
What seven?
The awakening factors of mindfulness, investigation of principles, energy, rapture, tranquility, immersion, and equanimity.
These are the seven principles that guard against decline.”
