“Observe the movements of the stars as if you were running their courses with them, and let your mind constantly dwell on the changes of the elements into each other. Such imaginings wash away the filth of life on the ground.”

“Dwell on the beauty of life. Watch the stars, and see yourself running with them.”

“Everything is only for a day, both that which remembers and that which is remembered."Observe constantly that all things take place by change, and accustom thyself to consider that the nature of the universe loves nothing so much as to change things which are and to make new things like them. For everything that exists is in a manner the seed of that which will be.”

“Is your cucumber bitter? Throw it away. Are there briars in your path? Turn aside. That is enough. Do not go on and say, "Why were things of this sort ever brought into this world?" neither intolerable nor everlasting - if thou bearest in mind that it has its limits, and if thou addest nothing to it in imagination. Pain is either an evil to the body (then let the body say what it thinks of it!)-or to the soul. But it is in the power of the soul to maintain its own serenity and tranquility. . . .”

“Observe always that everything is the result of change, and get used to thinking that there is nothing Nature loves so well as to change existing forms and make new ones like them.”

“If you do the task before you always adhering to strict reason with zeal and energy and yet with humanity, disregarding all lesser ends and keeping the divinity within you pure and upright, as though you were even now faced with its recall - if you hold steadily to this, staying for nothing and shrinking from nothing, only seeking in each passing action a conformity with nature and in each word and utterance a fearless truthfulness, then the good life shall be yours. And from this course no man has the power to hold you back.”

“Humans have come into being for the sake of each other, so either teach them, or learn to bear them.”
