hmm, I'm trying to find words to try and explain it. They show me in pictures. It is akin to a muscle, just like our arms and legs. As we "use" it, we build it stronger. The pineal gland has fluid in it and it conducts electricity and this electricity sparks a different sense. That's all I can do to explain it lol. Seems lame in words. It's pretty cool the way they show me.
