Itivuttaka 85
This was said by the Blessed One, said by the Arahant, so I have heard: “Remain focused, monks, on foulness in the body. Have mindfulness of in-&-out breathing well-established to the fore within you. Remain focused on the inconstancy of all fabrications. For one who remains focused on the foulness of the body, the obsession with passion for the property of beauty is abandoned. For one who has mindfulness of in-&-out breathing well-established to the fore within oneself, annoying external thoughts & inclinations don’t exist. For one who remains focused on the inconstancy of all fabrications, ignorance is abandoned, clear knowing arises.”
Focusing on foulness
in the body,
mindful
of in-&-out breathing,
seeing
the pacification of all fabrications
–ardent
always:
he is a monk
who’s seen rightly.
From that he is there released.
A master of direct knowing,
at peace,
he is a sage
gone beyond bonds.
