A Bodhidaoist affirms their dedication to learning from the wisdom traditions of Buddhism, Daoism, Stoicism, and Humanism. Where is one to begin?
Start with Stoicism.
For most Westerners, it is best to begin with Stoicism because it is the closest to Christianity. The fact is that Christianity borrowed a lot from Stoicism.
You should begin by reading three books by actual Stoics. The Discourses and Selected Writings by Epictetus, the Meditations by Marcus Aurelius, and the Letters from a Stoic by Seneca. Versions can be found online for free.
My favorite book by a modern author about Stoicism is Stoicism and the Art of Happiness by Donald Robertson. Another good one is A Guide to the Good Life: The Ancient Art of Stoic Joy by William Irvine. Ryan Holiday, John Sellars, and Massimo Pigliucci have some good books as well.
But be careful you don’t get in the trap of reading about Stoicism but never living it. It’s easy to do.
