Is this a BIPOC only sit? Are white people also welcome? What if I’m not Buddhist?

It's not a Buddhist meditation. Or a not-Buddhist. It's for beginners and advanced folks. It's for anyone who could use an extended period of time of intentional practice, whether to start, build, maintain or invigorate the practice you have.

If you have a history of mental health concerns, please check with your mental health professional that meditation is advised for your particular situation.
