I think he means, Will all this brain wave entrainment that I use while doing activities(studying,and so on)cause me to be dependent on it for effectiveness.
In other words after using it for a while, can I do without and still perform at the same effectiveness? Or not?

Well all I can say is it's "enTRAINment". It trains your brain. For example if you've been in "Beta" survival stress mode then using a hemi-sync CD combined while consciously relaxing can help "Train" your brain to reach that state more easily. Brain wave binurals just help pull your brain back to a desired state and have the ADDED effect of helping YOU reach that state on your own more easily. I sure at some point you won't need it as much because your brain will be so well trained and then Memory Supercharger and Personal Genius would work even better than before and you'll be more receptive to Paul's inductions as well. I notice that when I'm really stressed it's harder for me to get with the flow of Paraliminals. Just know that you don't need BWG. It's a tool that catapults you onto your own. Refer back but don't depend.
Also remember your beliefs control how your mind works as well. So if you start believing that you'll need it to do something effectively then you could very well create a huge pickle out a really faulty belief. I think 60 percent of something working has to do with your belief, and also your willingness to see the unlimited possibilities. You'll be fine.
