Thank you!! I make this distinction all the time. The other misconception is that stoicism is the antithesis of spirituality. So wrong. Go back in time and tell Marcus Aurelius and Seneca and Epictetus that they weren't spiritual and see if they can control their laughter. The stoic philosophy is depicted in modern time by the uber spiritual serenity prayer, which stands for the only thing we can control is our reactions and attitudes. You may enjoy this story of mine, which discusses Dr. Purcell's essay on the Aztecs and Epictetus: https://medium.com/channspirations/the-serenity-prayer-df758d99c956
