Yes, that's very interesting.
Some people seem to be unaffected by the many novel or increasing environmental threats of modern life.
Some, like me, can detect the reality of subtle things like earth energy lines, geopathic stress lines and I'm sure lots more when I 'put my mind' to it - but also seem to be unaffected.
Others are seriously affected by several of such things.
What's the difference between those who are affected and those who apparently aren't? Note that awareness (or denial) of the reality of such phenomena doesn't explain the difference in affect.
Is it that everyone is affected but some are too robust in health, or too youthfully busy to presently notice effects that will hit them later?
Or is it that some really are immune, or have some conscious or unconscious way of protecting themselves?
My feeling is that the modern world is going to get more and more unstoppably 'modern', in ways that we (arguably) benefit from, but also many of us dread.
Maybe we'd better look out for ways to 'get used to it', so we can relax and 'get a life' in the modernising world.
Maybe we need less of a mentality of Protection, more of Adaption.
Immunity is just that - a capability to adapt and transmute, on-the-fly, whatever comes. Threats are nothing new - Immune systems heve been handling novel 'threats' (such that 'threat' is a poor word for it) since the year dot. It's true that new 'threats' are appearing so fast nowadays - (chemical pollution, bad foods, suspect GMOs, EMF smog, strengthening of age-old Geopathic effects etc) that Immunity is struggling to keep up.
The 'Blessings' article linked to sounds like an excellent 'get used to it', 'relax', get a life' approach.
Another approach is something like homeopathic, or 'resonance medcine' in general - which is the end are just ways to remind, assist and co-operate with our own immune system, to handle the 'threat', when it may have lost the plot or need some help.
Conscious Intent is a vital part of 'resonance medecine' - and another way of saying that is Blessing', or naming the game, consciously offering and inviting co-operation with our inner parts.
So I wouldn't tar a 'Blessing' approach a 'Billy Graham' brush (who was/is a dubious character). I'd ask myself - do I want to live in fear and Protection, or in confident, relaxed Immunity?
