I have been watching a local herd of beef cattle, over the recent frosty weather.
The thing is, where they have bedded down, very noticable in the frost, and as I know the fields so well, I have noted that they tend to sleep on the spirals that I dowse, not only that, they clearly turn around in the direction that the spirals are dowsable .
So, if as I know, yes know, that the stones spin the energy around them, the term corral is not too far off, but not only for livestock, other animals, people , may prefer to sleep in this space.
As now, churchs are places of refuge, and opposing forces wont enter them, perhaps preditors wont enter them, and so all would feel safe in this sacred space.
