I have never come across JWs sanctioning visual imagery and similar "new age" customs before. I am rather surprised there isn't a JC convened since they are obviously getting wrapped up in Pagan thoughts and behaviors.
The WTS has so muddied the water on what is ok and not ok regarding blood - I wonder if all the possible options were explored, or whether it was just a blanket dogmatic "no blood (or fractions thereof, even though it might be ok)" attitude that prevailed.
Poor kid...
