Yo' Kyo,
Dude, you are so stoked! If you, being 16, are in the process to stretch and expand your gray matter in this way, I can only imagine what depths of understanding you will have when you reach my age. (31)
I am actually pretty interested as well about your question. I know that when I listen to talk radio or music I find that my reading skills go. I know that my mind gets distracted quite well with the audio. I am not sure about the better of the two. (to listen to music or not) This is my take.
My instincts tell me that listening to music while in the PR part itself (step 3) is not as beneficial as if you where reminding yourself of what you are in the process of trying to accomplish.
I am taking the advice o'Pete and go through 2 months of 5-10 books a day, Activating 1/week. I don't preview the book each time. (Let me know if that is correct or not fellow travelers)
When I do this, I don't spend the time focusing on the words, but focus on the feelings and process my mind is going through while PR. I try to hear the words seep from my sub-mind to my internal ears. I remember constantly that I not only want to further develop PR by successfully absorbing the information.
To add music on top of that would to me, be too much of a distraction. However, I could see that after I am comfortable with my skill in the PR process, I would love to kick on some Ministry and just absorb.
Ultimately, the verdict is still out on that one for myself. I would also be interested to see what others thought.
Till then,
BlkWolf
