The sacrifice which causes sorrow to the doer of the sacrifice is no sacrifice. Real sacrifice lightens the mind of the doer and gives him a sense of peace and joy. The Buddha gave up the pleasures of life because they had become painful to him.
Man is not equally moral at all hours, this is well known. If his morality is judged to be the capability for great self-sacrificing resolutions and self-denial (which, when continuous and grown habitual, are called holiness)
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].
I want our enemies to understand that don't think that their violent acts are going to cause this president to leave before the job is done. And I want our troops to understand we respect them and that the sacrifices they make are noble and necessary for peace.
Let us not only remember the past and its required sacrifice, let us also remember that we are responsible to build a legacy for the generations which follow us.
Live in the world without any idea of what is going to happen. Whether you are going to be a winner or a loser, it doesn't matter. Death takes everything away. Whether you lose or win is immaterial. The only thing that matters, and has always been, is how you played the game. Did you enjoy it? - the game itself - then each moment is of joy. You never sacrifice the moment for the future.
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.
When there is a choice about it, a great sacrifice is preferable to a small sacrifice, because we compensate ourselves for a greatone with self-admiration, which is not possible with a small one.
