In regards to the 12-color meditation (learned from the supercharging book), I have always followed the 2-dimensional diagrams that helps give you an idea of what to do. I realized recently that i've been following that diagram so rigidly that I was only filling up the colors from the inside out to the sides, rather than including the front and back.

So this isn't really a tip, it's just a reminder for those like me who are doing the meditation and not incorporating the entire body 360 degrees all around.

So like whenever I'm doing an outer color and i'm in a sea of ... green let's say, remember the colors aren't just to your left or right,but in front of you and behind you, that's what i'm trying to say, hehe.

And last but not least, adding that metallic-paint-like sparkle to every color helps it penetrate your body with a lot more ease! try it!
