“Beautify your inner dialogue. Beautify your inner world with love, light and compassion. Life will be beautiful.”

Context: So live your life that the fear of death can never enter your heart. Trouble no one about their religion; respect others in their view, and demand that they respect yours. Love your life, perfect your life, beautify all things in your life. Seek to make your life long and its purpose in the service of your people. Prepare a noble death song for the day when you go over the great divide. Always give a word or a sign of salute when meeting or passing a friend, even a stranger, when in a lonely place. Show respect to all people and grovel to none. When you arise in the morning give thanks for the food and for the joy of living. If you see no reason for giving thanks, the fault lies only in yourself. Abuse no one and no thing, for abuse turns the wise ones to fools and robs the spirit of its vision. When it comes your time to die, be not like those whose hearts are filled with the fear of death, so that when their time comes they weep and pray for a little more time to live their lives over again in a different way. Sing your death song and die like a hero going home.

Context: All idealization makes life poorer. To beautify it is to take away its character of complexity — it is to destroy it. Leave that to the moralists, my boy. History is made by men, but they do not make it in their heads. The ideas that are born in their consciousness play an insignificant part in the march of events. History is dominated and determined by the tool and the production — by the force of economic conditions. Capitalism has made socialism, and the laws made by the capitalist for the protection of property are responsible for anarchism. No one can tell what form the social organisation may take in the future. Then why indulge in prophetic phantasies? At best they can only interpret the mind of the prophet, and can have no objective value. Leave that pastime to the moralists, my boy.
