Imagine that you are creating a fabric of human destiny with the object of making men happy in the end, giving them peace and rest at last, but that it was essential and inevitable to torture to death only one tiny creature ... and to found that edifice on its unavenged tears, would you consent to be the architect on those conditions?
Too high a price is asked for harmony; it's beyond our means to pay so much to enter on it. And so I hasten to give back my entrance ticket ... It's not God that I don't accept, Alyosha, only I most respectfully return him the ticket. It's not that I don't accept God, you must understand; it's the world created by Him I don't and cannot accept.

--F. Dostoevsky

If you were to destroy in mankind the belief in immortality, not only love but every living force maintaining the life of the world would at once be dried up.
If the devil doesn't exist, but man has created him, he has created him in his own image and likeness.
Beauty is mysterious as well as terrible. God and devil are fighting there, and the battlefield is the heart of man.
Love all God's creation, the whole and every grain of sand of it. Love every leaf, every ray of God's light. Love the animals, love the plants, love everything. If you love everything, you will perceive the divine mystery in things. Once you perceive it, you will begin to comprehend it better every day. And you will come at last to love the whole world with an all-embracing love.

 --F. Dostoevsky
