I think it's definately helped now. I have had a fixed sacrum for many years, no amount of adjustments could shift it. It now seems much looser, I am getting clicks there now. I know it's also connected to Kidney energy and I have Andreas's Kidney ener-chi art as well - I think they've both helped for the manual adjustments I swop with another kinesiologist. I have been wearing my taychon disk in my sacrum area daily for 2 weeks when I play Tai Chi in the mornings.
As to chakra balancing, I can't balance it on my head or 3rd eye! I do like wearing it around my lower Dantien though, that feels nice although I'm not sure what it's up to.
