What is a charitable heart?
It is a heart which is burning with Love for the whole of creation
– for men and women, for the birds, for the beasts, for the demons
– for all the creatures.
One who has such a heart cannot see or call to mind a creature without one’s eyes filling with tears by reason of the immense Compassion which seizes the heart.
That is why such a one never ceases to pray also
– for the animals, for the enemies of truth, for those who do one evil,
moved by the infinite Pity which reigns in the hearts of those who are becoming united with God.
— Isaac the Syrian (Isaac of Nineveh)
