"The Meditation"
"The Meditations" or "To Myself" by Marcus Aurelius Antoninus the most notable stoic philosopher (beside Seneca). Since my term paper is about Marcus Aurelius and his Late Stoa Philosophy,this book is the primary literature. If you want to know what lately-most-used-term 'stoic' mean and what ascetic life is all about you should definitely read it! :D I'll feel free to call it "Western Bushidō"! ;) These are some quotations:
"The universe is change; our life is what our thoughts make it."
"Think not disdainfully of death, but look on it with favor; for even death is one of the things that Nature wills."
"Never let the future disturb you. You will meet it, if you have to, with the same weapons of reason which today arm you against the present."
