“I think you should be careful what suggestions you put into the air, Scyrilla,” said Helia. “You never know which god, disturbed of his or her rest, will play with a notion. You could be sorry. For all their power, gods are highly suggestible. Almost like children.”The Brides of Maracoor, by Gregory Maguire, pp. 252 – 253
In a pagan world, this is very true, very insightful, and also a basic safety precaution to keep in mind.
