Geoff: "I regret, Lyndon, that you have omitted to answer my question as to whether dowsers should be ungrouded."
I do not accept that being in the moment is the same as being grounded. Being in the moment may be the method by which grounding is achieved but it is not grounding in itself. Grounding is a state in which energy flow is established, while being in the moment is related to consciousness which, from my (deviceless) dowsing research, is not energy.
Energy, they say, follows thought (an aspect of consciousness) so to confound the two seems a tad perverse.
The difficulty in understanding a given phenomenon lies, imo, in tradition. Traditions for some strange reason isolate themselves from other traditions and refuse to look beyond their own narrow perspective of nature. When we enter a tradition such as dowsing we tend to swallow the terminology (which may have been coined in a less enlightened age) whole without first relating it to other traditions or modern scientific modes of thought which are based on the principles of matter and energy. Matter and energy (plus consciousness) are the principles by which modern man understands the world in which he lives and he deviates from this at his peril.
In my answer to you I assumed the term 'grounding' to indicate that, to be effective, a dowser has to become part of an energy circuit which he establishes either by concentration (being in the moment) or by invocation (calling on higher powers) before he can be effective in the task of dowsing for whatever purpose he wishes to use it. Being a deviceless dowser I do not have experience of dowsing in the field so cannot answer your question from personal experience. I gave a theoretical answer based (I hope) on the scientific perspective in the hope that it would shed some light on your deliberations.
You are not alone in having difficulty in understanding the things I say. Sometimes I read ancient posts and wonder what the heck I was talking about. All I can say in my defense is that I understood it at the time.
