The Kilted Heathen

Superstitions I more view as "folk wisdom". Walking under a ladder is bad luck - you might get hit on the head with falling tools. Opening an umbrella inside is bad luck - you might break it or something. Breaking a mirror is bad luck - it's dangerous, and mirrors are expensive to replace. Some certainly have no such sense to them, such as black cats and horseshoes, and act more as charms and fetishes.
Religious faith, on the other hand, pertains to higher existence. While the fate of your soul might not rest on breaking no mirrors in your lifetime, to some it often does with which god you determine to follow; good or evil. The fate of ones crops or homestead could be at risk if proper tribute isn't paid to land spirits, or warded against those for whom there is no appeasing. Things that have no provable rationale, but are still ingrained within a cultural identity.
