they're called paraliminal meditations and they do use the same techniques as the other paraliminals - you know, this voice in the left ear and this voice in the right ear, and they do ask that we use the stereo headphones with them. The added layers are what I reckon makes them so good. The second half of the CD can be played as background music, the first half is pretty powerful and I don't think I'd like to be driving while I was listening - I'm pretty used to listening to paraliminals and audio meditations, but I've gone much deeper into nothing very quickly and several times now since using these. I personally find both parts of the CD very powerful and use the whole thing as a meditation.
I love them all, but the health and spiritual growth meditations are especially exceptional.
