In order to develop the willpower it takes to sacrifice, you must first realize that spending all your time and energy pursuing material comforts means you will eventually suffer. It's all about positive and negative consequences. It's very important to be aware that there are long-term consequences [for every action].
In the military, you learn the essence of people. You see so many examples of self-sacrifice and moral courage. In the rest of life you don't get that many opportunities to be sure of your friends.
Behave when away from home as though you were in the presence of an honored guest. Employ the people as though you were assisting at an important sacrifice. Do not do to others what you would not like yourself. Then there will be no feelings of opposition to you, whether it is the affairs of a state that you are handling or the affairs of a family.
We do not admire, we hardly excuse, the fanatic who wrecks this world for love of the other. But what are we to say of the fanatic who wrecks this world out of hatred of the other? He sacrifices the very existence of humanity to the non-existence of God. He offers his victims not to the altar, but merely to assert the idleness of the altar and the emptiness of the throne. He is ready to ruin even that primary ethic by which all things live, for his strange and eternal vengeance upon some one who never lived at all.
Very much indeed of what we call moral education is such an artificial modification and perversion of instinct; pugnacity is trained into courageous self-sacrifice, and suppressed sexuality into religious emotion.
I worship God as Truth only. I have not yet found Him, but I am seeking after Him. I am prepared to sacrifice the things dearest to me in pursuit of this quest. Even if the sacrifice demanded my very life, I hope I may be prepared to give it.
We are not deceived by their pretenses to piety. We have seen their kind before. They are the heirs of all the murderous ideologies of the 20th century. By sacrificing human life to serve their radical visions - by abandoning every value except the will to power - they follow in the path of fascism, and Nazism, and totalitarianism. And they will follow that path all the way, to where it ends: in history's unmarked grave of discarded lies.
I see the Jedi mission as giving up a normal life in exchange for protecting the innocent. It's a life of sacrifice. There are rewards, but also a certain degree of sterility.
Active nonviolence of the brave puts to flight thieves, dacoits, murderers, and prepares an army of volunteers ready to sacrifice themselves in quelling riots, in extinguishing fires and feuds, and so on.
This state of mind, which subordinates the interests of the ego to the conservation of the community, is really the first premise for every truly human culture... The basic attitude from which such activity arises, we call-to distinguish it from egoism and selfishness-idealism. By this we understand only the individual's capacity to make sacrifices for the community, for his fellow men.
