Hi Koko
I too have strong Christian beliefs and I don't know enough about paraliminals to make a comparison to hypnosis etc. So in the meantime until new information comes to light for me, I have chosen to select what I consider to be 'safe' mp3s such as the Sleep Deeply mp3 and the Abundance mp3.
We all need to go to the doctors from time to time and we all need to provide for ourselves too so that is how I look at it. For now that is!
