my family has a family friend who is all over the hulda clark idea, but my stepdad actually tried to use it and he still died of cancer. he wasn't somebody i could effectively advise on nutrition so we'll never know if that could have helped. there was a time where i was even coerced into using this device but i never noticed any benefit. my understanding of the device is that the analyses are extremely subjective and while i can envision frequencies being used to kill pathogens, i view the concept as more of a mechanical version of pharma, one that won't address any underlying imbalances, so the nutrition component HAS to be there or you just have a treatment, not a lifestyle shift.
synesthesia, that is fascinating, nice call COB. i think seeing auras fits into this picture extremely well and ought not to be viewed as a separate phenomenon. it could be possible that happy dancer sees things that others would sense via smell/VNO, such as pheromones.
