Does dowsing always fall into the category of divination, a form of
idolatry?

Clearly the world is full of spirits and some of them are unclean. Does
that imply that some spirits are clean? When dowsing, is it possible to
get the help from clean spirits?

If one prayed to Yahweh for help in locating water, healing, or some
other need, why is that not dowsing? Only because when Yahweh is being
addressed for one's needs, then it no longer meets the definition of
idolatry, correct?

So, in other words, is dowsing always a Biblically forbidden divination,
or could it with narrower parameters be no different than answered
prayer? So, if the parameter is that the provider of the knowledge is
Yahweh and only if it be His will for us to know, then it's answered
prayer, right?
