Hestia always makes herself known to me whenever there are difficulties on the home front. Whenever the difficulties get too intense a sort of calming influence can be felt, by me, breaking through the dramas and tensions. Sometimes I dream about a housekeeper at such times too and I always think of that as Hestia letting me know she is around us.
The kind of image I get of her is a calm, middle aged woman, not so much motherly, more of a housekeeper. The closest I can describe her so you have an idea of what I mean is someone who looks a little like Lynda Bellingham - of the OXO ad fame.
As Hestia is Goddess of Hearth and Home I think this imagery I have suits her well.
