yamabushi monks hate this one weird rock trick

Someone discovered meditation exists and decided to cosplay as a Japanese mountain monk by making up the most unhinged "secret technique" involving washing your face and touching a boring rock. The parenthetical warning about rocks that "don't resemble anything" is where this transcends into pure unhinged territory—as if the danger is that your palm-sized meditation rock might betray its true form as a hidden duck. This is what happens when people learn one vaguely Japanese word and immediately become wellness gurus.
