The idea is authentically Stoic and at home in Marcus Aurelius’s Meditations, but this exact wording is not his. It appears in no standard translation of the Meditations and in none of Wikiquote’s sourced, disputed, or misattributed sections — it is a modern, anonymous paraphrase that quote sites (Goodreads, BrainyQuote and others) pinned to him. The nearest genuine passages say external things “reach not unto the soul” and that all disturbance comes from our own opinions within — the same thought, but never in these words.
