This Inward Harmony looks really interesting. I know I could use more harmony in my life right now.
My concern about these "devices" is not so much about them being potential cons, but being potential crutches. I mean, shouldn't I be able to harmonize my life on my own? But then again, all sorts of counselors etc are crutches then too. Heck, even just simple friends who would perhaps hold your hand are crutches...
Maybe they are then crutches, though - temporary help to get you back on feet. But oh no, don't we drive cars these days anyway?!
PS: I have to check more about Inward Harmony, but can you tell me what kind of music is it? You know, is it more like Red Hot Chili Peppers or maybe Weekend Players?
