Lyric discussion by Frigg 

Cover art for Our Mother the Mountain lyrics by Townes Van Zandt

I think it is something rather mythical. Maybe a girl possessed by the demoness Lilith. It is said that she appears a beautiful woman at first and then turns to something of an old hag. He is also said to harm newborns, she is supposed to be responsible for still births and crib deaths. There's a lot more about her that I don't really feel like typing. Google Lilith .
