Not from any known translation of the Meditations. Quote is attributed to Marcus Aurelius, e.g. in the 2006 book: Personal Best: 10 lessons to help you achieve your true potential, page 195. The quote could be a paraphrase of a line at Meditations iv. 3: "that things do not take hold upon the mind, but stand without unmoved, and that disturbances come only from the judgement within" (Farquharson translation)
