Bright-minds

I heard about something called Brain Gym. At first I thought it to be exercises to help focus, so kids (or anyone) could concentrate and not stay distracted by one's thoughts or the many things happening around you. There are indeed exercises but I also read a couple of articles warning about Brain Gym, one said the information about it was full of new age terminology. Another talked about a woman who uses it extensively as also teaching yoga. Others in England just ridiculed it. I wonder if the exercises alone can indeed help one to concentrate so as to be able to read or do math, but if you get more into the program that then it might get into opening up yourself to influences that are of a spiritual nature. One place it talks about emptying your mind, and we know that the Bible talks about thinking about good things, whatsoever things are pure, just, lovely, of good report, not emptying our minds. So does anyone have any knowledge about Brain Gym? Could you let us know? Thanks!
