Yangmingism has been popular in China for centuries. I love the startlingly similarity of

心外无物， 事上磨炼

with modern western philosophy of life and psycho-therapy.

It’s not things that upset us, but our judgments about things – said the Stoics.

The Chinese learned to 修心，and Yangming told us to 知行合一.

No need to reach out for a cell phone, reply that angry message, or even sit for long hours of meditation: all the changes you need to be happier is within your inner citadel – your mind.
