Doing good to others is not a duty. It is a joy, for it increases your own health and happiness.
ZoroasterYour good thoughts, good words and good deeds alone will be your intercessors. Nothing more will be wanted. They alone will serve you as a safe pilot to the harbour of Heaven, as a safe guide to the gates of paradise.
ZoroasterIf one would have a friend, then must one also be willing to wage war for him: and in order to wage war, one must be capable of being an enemy.
