What is a merciful heart?
It is a heart on fire
for the whole of creation,
for humanity,
for the birds,
for the animals,
for demons,
and for all that exists.
By the recollection of them
the eyes of a merciful person
pour forth tears in abundance.
By the strong and vehement mercy
that grips such a person’s heart,
and by such great compassion,
the heart is humbled
and one cannot bear to hear or to see
any injury or slight sorrow
in any in creation.
For this reason, such a person
offers up tearful prayer continually
even for irrational beasts,
for the enemies of the truth,
and for those who harm him,
that they be protected and receive mercy…
because of the great compassion
that burns without measure
in a heart that is
in the likeness of God.
+ St. Isaac the Syrian
