I find it difficult to define my concept of the gods... I think the best way is to think of the 'everything is sacred' view, and that divinity is part of everything...
And as for the supernatural, it's to do with the powers of the mind, really... I don't believe Hecate, or whoever, is sitting about when she figures it might be okay to help me, more that the words and ritual focus a desire in my own mind, and make me more determined. The one thing I can't put into place with that is after death, as I do believe in reincarnation. Thinking about it too much makes my brain hurt!
At the end of the day, believing it makes me happy, and if it turns out not the be the case, so be it... if there's nothign after death, I lose nothing by hoping there is. If there is, so much the better: I get another shot at life.
