My husband was sitting across from me (trying to relax and watch TV) while I read this book and kept catching me trying to read his aura. :P hehehe
I could actually see it!! It looked like heat... imagine that wavy look of heat over a road on a blistering hot day, or above the bbq grill. I couldn't make out the color (since he kept telling me to knock it off, and...)the lighting in the room and the colored walls interfered. I never got around to trying the other techniques in the book, but it was interesting and I enjoyed reading it. You can practice on pets or plants... My cats don't like it either and unfortunately I'd killed all my houseplants by then. I remember seeing the aura of a plant when I was little, but I thought it was just because I had a fever and it was freaking me out.
I wouldn't mind reading the book again and trying the techniques on a more willing subject. ;)
