im a new to these stuffs, but i see that many things here, not just photoreading, is about getting to that certain brain state, like the paraliminal cds, etc.. i want to give these a try..

with this intention, i downloaded this brainwave generator (for free) which it seems that it gives all this brainwave technology for free.. e.g. to get into deep relaxation, meditative.. i know they don't have the function of the paraliminal tapes described here.. but just on relaxation, meditative.. does anyone know whether it's effective.. or compared to Paul's cd here.. wht's the difference? or the effectiveness..
