Consciously, neither and both. Just relax and listen down the middle... allow yourself to repond to the voice or side that feels right...you find that sometimes you listen to the one voice following any instructions given there and other times the other. Changing as you listen... You might even find that you listen to neither voice as you go even deeper and almost to sleep. Go with the flow, just relax and enjoy it.
The only thing you need to do is tell yourself why you are listening to the tape. Eg for the memory supercharger you might say... for better recall of the book I photoread today. Or better remember names of people I meet. You get to have fun and decide how you want to use the tape. When you tell yourself specificly why you are listening to the tape you enjoy more benefits.
Listen daily for a week for just general listening and in relation to enhancing your photoreading skills.
