::- ''O Youth: Do you know that yours is not the first generation to yearn for a life full of beauty and freedom? Do you know that all your ancestors felt as you do -- and fell victim to trouble and hatred? Do you know also, that your fervent wishes can only find fulfillment if you succeed in attaining love and understanding of men, and animals, and plants, and stars, so that every joy becomes your joy and every pain your pain? Open your eyes, your heart, your hands, and avoid the poison your forebears so greedily sucked in from History. Then will all the earth be your fatherland, and all your work and effort spread forth blessings.
