You shall love peace as a means to new wars - and the short peace more than the long.
Your 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.
Seek your happiness in the happiness of all.
When you are in doubt abstain.
In doubt if an action is just, abstain.
If 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.
