I was wondering what is the best way to listen to paraliminal tapes - actively or passively?

In a tape such as NBG or IPM, we are asked to visualize the person we are trying to model. This seems to be an active process, since we have to actually do something, versus just listening to the tapes.

The instructions mention affirming our goals prior to listening to the tapes. After that is there nothing, such as actively visualization, we have to do apart from listening to the tapes?

I would love to get any ideas you have to get the best out of these tapes.

Thanks.
