I found a lovely YouTube channel called Sleepy Monk, which has a playlist called "The Zen Path".

Each of the fourteen videos focus on a specific Buddhist principle, or multiple principles, on the path to inner peace.
I added a fifteenth Buddhist principle: Equanimity. Its significance was made clear in a different Sleepy Monk video: Unshakable Mind.
