Buddhism arrived in the Americas long before Spanish Catholicism and British Christianity. So when Buddhism returned, it had a natural affinity for Native American traditions particularly of the U.S. Southwest and Mexico (Mesoamerica). This history was wiped from memory by European colonialism, but the core shamanic worldview remained.

We'll talk with a local Kizh/Tongva (L.A.'s pre-Columbus tribe) American Indian Buddhist, smudge with sage, use essential oils and crystals, talk about the world's largest pyramid (which is in America not Egypt), and complete the loop of the circle.
