Thanks for sharing that info, Lightning. So for the Thai monks, it's okay for them to have tattoos? That would contradict the Vairocana Buddha commitment also? Or do the Thai monks not have those commitments?
Actually if the commitment is to not harm your body, then piercing ears is also not allowed, nor plastic surgery. Though i guess it's logical that those are purely cosmetic and we should not indulge in the Eight Mundane Concerns anyway.
