"Bathing, and dress, and food regulation - all these have their proper value when they are complementary to the spiritual. .... That first, and these all help. But without it, no amount of eating grass... is any good at all. They are helps if properly understood. But improperly understood, they are derogatory... This is the reason why I am explaining these things: First, because in all religions everything degenerates upon being practiced by [the ignorant]. The camphor in the bottle evaporated, and they are fighting over the bottle."
