Oh yes, I would agree with that ... from the little bit I know about Crowley he was in connection with powerfull politicians. I would not compare them with amazone shamans though, because most of them are into healing. But this changes also, since there are now many self proclaimed shamans who found out there is a great demand of rituals in america and europe and now lots of them self made shamans travel the world and hold rituals for money ... not a good thing. The best thing that can happen in these rituals is that they have no quality at all ... worst thing is they can damage you and open you to the beings we discussed earlier.

would the "macrobes" find these folks more "desirable" to make "deals/pacts" with??? (They have something of VALUE to offer them!!!)

If the macrobes posses that kind of intelegence, which I am not sure about yet, yes, they would go for powerful people for sure. I even think that happened with Castaneda in a way. You probably know the death defier story. he gave Castaneda knowledge for his energy ... and in his later life the cult that formed about Castaneda became very weird and dameged many people, going this far that the females closest to him killed themselfes.
