And then Otso (from Finnish mythology, of all places) has ALSO come up and told me that I have the abilities of a bear-wife and need to be taught, as the Celtic gods are "too young to remember." (Most likely it's referring to how bears were driven to extinction in Britain quite a while ago.)
From what I can gather--which isn't much, since both of them are big on me using my intuition--a bear-wife is definitely a person with shamanic abilities. (Makes sense, since I'm also in a Native American influenced shamanic group.) They're also both hinting that this is not just an occupation but a title, much like how priestesses in some cultures are considered a deity's "wife."
Unfortunately, the only information I got on the phrase "bear-wife" that wasn't mistaken for childbearing was from a person's blog for their historical-fiction novel. The story is Norse-influenced and neither Celtic nor Finnish, but I'm taking any step in the right direction I can.
Anyone have resources on bear-worship, or what a "bear-wife's" abilities/duties might be? Also, websites and book recommendations are definitely helpful.
Edited to add: I've emailed Sannion at the House of Vines, and he'll get back to me around next week. Thanks a lot to wire_mother for recommending him.
