Listen down the middle. Don't focus on eaither ear. You will occasionally be attracked by the words one side or the other follow them if you like..

The two voices overwhelm the conscious mind so it shuts down. This is intentional so you can work with the other than conscious mind which is where habits and behaviours originate.

Just think of your goal answer the questions, listed in the booklet and asked asked at the beginning of the Paraliminal as best you can. This tells your other than conscious mind what you are working on and then just let go.
Yes, your conscious mind can wander or you can take a short nap.
