Thanks. Zelda is brimming with the occult, that's why I love it so much. So much symbology and esoteric meanings.
Occult is not what people think it is. It's nothing evil and demonic (although it can be). It's derived from Latin 'occultare', which means "hidden". It's simply hidden knowledge. A guy called Mark Passio explained everything very clearly in his presentation titled "De-mystifying the Occult". You can view it for free on YouTube.
