This is a worthy Blog-jacking. The following was hijacked from A Byzantine Christian in a Postmodern World.
'What is a charitable heart?'— asks St. Isaac the Syrian— 'It is a heart which is burning With charity for the whole of creation, for men, for the birds, for the beasts, for the demons-for all creatures. He who has such a heart cannot see or call to mind a creature without his eyes becoming filled with tears by reason of the immense compassion which seizes his heart; a heart which is softened and can no longer bear to see or learn from others of any suffering, even the smallest pain, being inflicted upon a creature. This is why such a man never ceases to pray also for the animals, for the enemies of Truth, and for those who do him evil, that they may be preserved and purified. He will pray even for the reptiles, moved by the infinite pity which reigns in the hearts of those who are becoming united to God.’ In his way to union with God, man in no way leaves creatures aside, but gathers together in his love the whole cosmos disordered by sin, that it may at last be transfigured by grace.
