It seems meditation isn’t the only way to get up into the air, although one can’t rule out that these Buddhist monks aren’t actually—heavily disguised as fun park patrons—practicing their asanas:
“The postures that a Buddhist deity assumes in a sculpture or painting are known as asanas.”
—Mudras in Buddhism, Rev. Jnana, Zen Dharma Teacher
Whatever the intent there seems little doubt they are having a jolly good time.
Super-sized fun even, albeit probably not hair-raising…
