I think it might depend on your Path. If you're a Knight, well, do you really believe your oaths if you're not guarding someone? Can someone really believe in being a priest without a flock to guide? That said, ascetics, monks and hermits were all very common in medieval Christianity, so there's support for "live in a cave for 20 years without bathing or interacting with people" as a route to getting closer to God.I think they probably could under the right circumstances, yes.
