Astral Travel takes an act of focus and imagination. If the meditation aspect of this is properly done, the physical body drops and you can go into a full blown O.B.E., rather than a simple projection on to the "Brain Screen" of the 3rd eye. The content of the astral planes, and the different 'planes' or different levels of rarefication can be measured in a non-absolute form as long as the system of measurement is in some way consistent throughout. These kinds of experiences take place generally in the high theta and low alpha brain wave states.
Dream Yoga, also known as lucid dreaming, is a method of inducing waking awareness while within your dream, and eventually experience wakeful awareness in a constant stream, such that you no longer need to wake up inside a dream, rather, the body sleeps, the senses shut down, and the dream arises. This wakeful awareness is characterized by low theta brain wave states.
I personally find Dream Yoga to be better suited to the work I do in Magick. However, this is not the normal approach, magick usually utilizes the astral realm and astral travel to get similar work done.
Any thoughts?
