I rate Diane Stein's Book Essential Psychic Healing as the best resource for all things hooks, barbs, and psychically gooey ... with Brennan's a more gentle 'airy' second ...

Seems to me, our powerful negative emotions send * some * of these nasty cords, hooks and barbs, while others feel to be not of earthbound origin. Once these books are read, I suspect anyone seeking harmony will be much more diligent with their thought and emotion projections.
