Ophiel suggests that you pick a familiar route, perhaps between two rooms in your house, and memorize every detail of it. Choose at least six points along it and spend several minutes each day looking at each one and memorizing it. Symbols, scents and sounds associated with the points can reinforce the image. Once you have committed the route and all the points to memory you should lie down and relax while you attempt to ‘project’ to the first point. If the preliminary work has been done well you should be able to move from point to point and back again. Later you can start the imaginary journey from the chair or bed where your body is, and you can then either observe yourself doing the movements, or transfer your consciousness to the one that is doing the moving.
Ophiel describes further possibilities, but essentially if you have mastered the route fully in your imagination you will be able to project along it and with practice to extend the projection. Ophiel states that starting to move into OBE will produce strange sounds. He says that this is because the sense of hearing is not carried over onto the higher planes, and that means that your mind tries to recreate some input, and just gets subconscious static. He asserts that the noises can take any form, including voices, malevolent, eerie, and get worse and worse, more and more disturbing, until eventually they peak and then just fade to a constant background hiss while one has OBE. Apparently, his ‘final noise’ sounded like his water heater blowing up. He says, anyway, to ignore the noises, voice or otherwise, as they are only static or subconscious rambling, and do not represent any being in any way, not even the self really.
