Wisdom from an ancient Zoroastrian book called Dinkard – Acts of Religion
Your religion is defined by your habits; religion is that which one does habitually. Five good habits: generosity, truth, virtue, eloquence, learning. Ahuramazda [God] is a friend, be a friend to everyone, your character is defined by how you take care of others. One should use wealth to help others and not be arrogant about it. The humblest and the best food is what you just ate. Ahriman [the devil] lives within you; and the fiercest demon is anger.
