Here is what I do for the third eye: I stick the disk under my pillow and sleep on it at night. I figure the third eye chakra is the same as upper dantien in taoism. My taoist master told me it is located in the middle of the skull, between the forehead and the back of the head (where it touches the pillow, I don't know what that acupuncture point is called in English). Anyway, third eye in scientific term is the pineal grand, which secrets malatonine at night and regulates the biological clock and such, so sleeping on the disk should have some benefit, right? (I hope.)

So far so good. I haven't lost any sleep over it yet. ^_- And although there hasn't been any dramatic change in my health, given that I have not been eating right or sleeping right lately, my energy level has been pretty good. I'll just keep using my disk. (I do alternate, sometimes putting it on my upper dantien/third eye, sometimes middle dantien/heart chakra, sometimes lower dantien/naval chakra, sometimes lower back/root chakra, while I sleep.)

BTW, I also put the disk under my feet when I do Quantum Touch, and it really gets the energy flowing (even I can feel it!) ^_^
