Meditations is a series of personal writings by Marcus Aurelius, Roman Emperor from 161 to 180 AD, recording his private notes to himself and ideas on Stoic philosophy. Marcus Aurelius wrote the 12 books of the Meditations in Koine Greek as a source for his own guidance and self-improvement. The Meditations is divided into 12 books that chronicle different periods of Marcus' life. Each book is not in chronological order and it was written for no one but himself. The style of writing that permeates the text is one that is simplified, straightforward, and perhaps reflecting Marcus' Stoic perspective on the text. A central theme to Meditations is the importance of analyzing one's judgment of self and others and the development of a cosmic perspective. As he said "You have the power to strip away many superfluous troubles located wholly in your judgment, and to possess a large room for yourself embracing in thought the whole cosmos, to consider everlasting time, to think of the rapid change in the parts of each thing, of how short it is from birth until dissolution, and how the void before birth and that after dissolution are equally infinite". He advocates finding one's place in the universe and sees that everything came from nature, and so everything shall return to it in due time.
