Rollin McCraty: I'll use an example. I'll try and be brief here. One of my grandmothers, when we were little kids, drove us crazy with her anxiety and worry. And now I've come to understand later in life that she lived through a time of the Great Depression.

And our son's all in World War II. A lot of reason to be worried and anxious. So if you hang out in a state long enough, that becomes your internal reference, your base, what we call your baseline. Right, so the brain feels comfortable when there's a match to the baseline and the current reality, current input.

So you spin up thought loops and anxiety to feel comfortable. As crazy as that sounds, that's the way our neurophysiology actually works. What Dr. Prebram proved, actually, this is not a concept.

Is that the only way to establish a baseline or change one is to change the input from the heart to the amygdala, because it's the main rhythm and source of rhythm. So by studying coherence, even 5 minutes a day, you're making sure you're really coherent. Now, that's the new input going up to the amygdala, so it starts to reprogram or establish that as your new baseline.

Cynthia: And that's when this becomes transformational in people's lives.

Rollin McCraty: Because there is no such thing as sustained change or a shift in awareness without shifting that internal baseline. So that's at the neurophysiological level, it's pretty straightforward, but then there's also the... our energetic system works the same way, right?
