Brendan:
That little mental fantasy which you go through--the hang gliding--sounds remarkably similar to the mental exercises which some of the government's "official" remote viewers used to go through to prepare for their sessions. It sounds to me, though, that you are under the mistaken impression that you are going to experience a highly successful RV session every time. Well, that's not going to happen.
To me, ritual is important. I try to do the same thing every time. I feel this trains the mind so that, when I do X and Y, it knows to begin to get into the state of consciousness conducive to remote viewing.
I always go through a progressive relaxation exercise, alternately tightening and then relaxing the major muscle groups, from head to toe (actually, I think I go from toe to head!). But even more important is the breathing. I try to do the "belly" breathing which is taught in yoga and meditative practices. I very gradually slow my breathing somewhat. After doing the relaxation and breathing exercises for two or three minutes, I then start to blank out my mind. I go through this visualization exercise in which I try to picture a particular gray image in my mind--nothing else. At the same time, I try to think of nothing. This is the most difficult part--to still the always-active human mind.
If I am successful, somewhere between 5 and 10 minutes after I start, I will enter the zone and the image of the target will start to appear. Especially if the target is a 2-dimensional picture, and especially when I was just beginning RV, the images would flicker in my mind's eye.
