This is to be done by one skilled in aims
who wants to break through to the state of peace:
Be capable, upright, & straightforward,
easy to instruct, gentle, & not conceited,
content & easy to support,
with few duties, living lightly,
with peaceful faculties, masterful,
modest, & no greed for supporters.

Do not do the slightest thing
that the wise would later censure.

Think: Happy, at rest,
may all beings be happy at heart.
Whatever beings there may be,
weak or strong, without exception,
long, large,
middling, short,
subtle, blatant,
seen & unseen,
near & far,
born & seeking birth:
May all beings be happy at heart.

Let no one deceive another
or despise anyone anywhere,
or through anger or irritation
wish for another to suffer.

As a mother would risk her life
to protect her child, her only child,
even so should one cultivate a limitless heart
with regard to all beings.
With good will for the entire cosmos,
cultivate a limitless heart:
Above, below, & all around,
unobstructed, without enmity or hate.
Whether standing, walking,
sitting, or lying down,
as long as one is alert,
one should be resolved on this mindfulness.
This is called a sublime abiding
here & now.

Not taken with views,
but virtuous & consummate in vision,
having subdued desire for sensual pleasures,
one never again
will lie in the womb.
