This was said by the Buddha, the Perfected One: that is what I heard.
“Enjoy retreat, mendicants, love retreat. Be committed to inner serenity of the heart, don’t neglect absorption, be endowed with discernment, and frequent empty huts.
A mendicant who enjoys retreat can expect one of two results:
enlightenment in this very life, or if there’s something left over, non-return.”
The Buddha spoke this matter.
On this it is said:
“With minds at peace, alert,
mindful and meditative,
they rightly discern the Dhamma,
unconcerned for sensual pleasures.
Delighting in diligence, peaceful,
seeing fear in negligence,
such a one can’t decline,
and has drawn near to extinguishment.”
This too is a matter that was spoken by the Blessed One: that is what I heard.
