But when the blast of war blows in our ears,
Then imitate the action of the tiger;
Stiffen the sinews, summon up the blood"

"Many that live deserve death. And some that die deserve life. Can you give it to them? Then do not be too eager to deal out death in judgement. For even the very wise cannot see all ends."

A simple enough statement that, when you really think about it, is really quite profound.
"Greater love has no man than this, that he lay down his life for his friends."
