[PickEmUp]

You know there's an author called Ophiel, who wrote several books about astral projections and magic. In one of them (Art and practice of astral projection) he explains 4 methods for projecting, one of them being "the body of light" (or so). According to the procedure, you have to create an astral body (not the one created automatically during separation, but another one designed "ad hoc").

So far the story isn't much interesting, but the important thing comes next. That astral double has to be imbued with "energy" or "life" (wouldn't know how to tell). To do so, Ophiel claims that the banishing ritual (of the Golden Dawn) practised by the astral double under the control of its creator does the trick.

It is obvious that before doing that all you have to be able to project yourself so you can see what's going on in the other side. According to the author as you go on with your practice a new body starts to appear when you project. When formed enough you can then start to make him practice the ritual.

The advantage of this all is that you always will have a projectable double, so projections happen more easily, and the double can also be used for other magical purposes.

That's another way to energy-work in the astral...
