The Crystal Light Bed is used by various practitioners around the world although it was invented by someone named John Of God, who sounds plenty qualified to me right there. One such is Kalisa Augustine (Kalisa Of Brooklyn), who, according to her website, uses spiritual technology and quantum alchemy to detoxify and purify the electromagnetic field, and Lord knows somebody needed to do that after all these years of neglect. Quantum alchemy is best left to the most certifiable masters of charlatanism, so it is comforting to note that Kalisa is quite blonde and has a nice set of credentials on her.
Ms. Augustine of Brooklyn goes on to explain that a crystal's natural structure is a six-sided prism with a terminated end. You definitely don't want the kind of end that goes on and on. This is not actually accurate with regard to any number of crystals I can think of, but it does describe quartz, so we'll let it go this time. She says crystals share this configuration with water and energy molecules.
[Energy molecules are principally composed of excitement atoms and zest, and remain mysterious to science to this day.]
In a nutshell, Kalisa's crystal bed is a "multisensory, meditative, cleansing experience that takes you into greater realms of depth." In fact, you can't really get much deeper.
I am not by nature wooful, but I accept that I too have at least seven chakras, in the same way I accept that I harbor a spleen, somewhere. I'm not intimate with them. The meridians are the pathways for the qi between the various chakras, as I understand it, and it's important to keep them reamed out so you don't clog your life force. This is all somewhat more challenging for me, because one side of my chest--for the moment, we're going to refer to these as "sides of my chest"--is much bigger than the other side of my chest, and that throws off the meridians, which have to make a little pivot halfway to my brain. In general, any sort of reboot of my spiritual body is going to be problematic, because I haven't even taken it out of the box yet.
Basically, the 12th chakra is out there with Pluto, and I hope they're having a good time. We're not going to worry about it now. It's not practical to make a Crystal Light Bed for all the chakras that might potentially be found. You'd end up sleeping inside a geode.
