Glowing Embers1
Thus have I heard:
The Exalted One was once staying near Sāvatthī
at the Jeta Grove in Anāthapiṇḍika's Park.
And there the Exalted One addressed the brethren, saying:
"Brethren!"
"Master!" responded those brethren.
The Exalted One said:
"Body, brethren, is (a mass of) glowing embers.
Feeling is a mass of glowing embers.
Perception is a mass of glowing embers.
The activities is a mass of glowing embers.
Consciousness is a mass of glowing embers.
So seeing, brethren, the well-taught Ariyan disciple feels aversioned1 from body,
from feeling,
from perception,
from the activities,
from consciousness.
Being averse
he is disgusted by them;
by that disgust he is released;
by that release he is set free;
knowledge arises:
in the freed man is the freed thing,
so that he knows:
"Destroyed is rebirth;
lived is the righteous life;
done is the task;
for life in these conditions
there is no hereafter."
