Constantly regard the universe as one living being, having one substance and one soul; and observe how all things have reference to one perception, the perception of this one living being; and how all things act with one movement; and how all things are the cooperating causes of all things which exist; observe too the continuous spinning of the thread and the contexture of the web.
Marcus AureliusAll things are in the act of change; thou thyself in ceaseless transformation and partial decay, and the whole universe with thee.
Marcus AureliusOnly to the rational animal is it given to follow voluntarily what happens; but simply to follow is a necessity imposed on all.
Marcus AureliusArt thou angry with him whose armpits stink? Art thou angry with him whose mouth smells foul?
Marcus AureliusBecause your own strength is unequal to the task, do not assume that it is beyond the powers of man; but if anything is within the powers and province of man, believe that it is within your own compass also.
Marcus Aurelius
