Cynthia: One question that Barbara asks is related, actually, to one of mine. So, Barbara asks, how do pacemakers affect heart coherence? And mine, sort of related to that, is, being that we're conductors of EMF, and you've so beautifully elucidated that, and now that we're living in a world where it's difficult not to be bathed in EMF from digital technologies. And towers, has that been measured at all, just in terms of how does that affect the EMF field of the heart, if at all?

Rollin McCraty: Yeah, it's really two questions there.

Cynthia: Oh, okay.

Rollin McCraty: On pacemakers, that was the first one. Most pacemakers, if you're a medical doctor, I didn't realize that, would know that most pacemakers or demand pacemakers, they only kick in if the heart's going into an arrhythmia or heart rate drops too low, so most of the time they aren't being paced. So, you can still see these subtler effects of our emotions being reflected in the rhythms of the heart and these types of things. Just normal and do the same practices.

If you're being constantly paced, you will not have normal heart rate variability, so you won't be able to see those rhythms, but that doesn't mean that using these techniques and heart-focused breathing doesn't have the same benefits. Because this is largely an energetic system shift that we're making. That's actually above that level of the physiology. So, a little more complex answer, but hopefully that'll give enough of a thing there.

Cynthia: Thank you.

Rollin McCraty: So, on the second question, I had the pleasure, actually, in a way, honor many, many years ago, of meeting a guy who was pretty famous in the field of bioelectromagnetics, a guy named Dr. Ross Aity. Who did a lot of pioneering work in the original research scene. Living systems and cells and all this kind of stuff respond to external electric and magnetic fields.

And to make a very long story short, what he found was that, yes, there can be very strong nonlinear effects from a very weak field. But, that there are windows, what do you call windows? That the external magnetic or field has to be of very specific frequency and intensity to have those nonlinear effects, these windows. As it turns out, those windows are the same frequencies and levels of other biologically generated fields.

Like hearts and brainwaves. Amazing, actually, that he's able to show this.

Cynthia: Yeah.

Rollin McCraty: So, what's way outside of those windows are things like cell phones, and they're radically different, they're whole different octaves of different frequencies. Now, that doesn't mean, at the same time, I wouldn't choose to live under a high-voltage power line, right? Or sleep with my cell phone in my head, but… so there's some common sense here, I think, as well. And at the same time, a lot of cell phone manufacturers know that.
