Heartmath institute!!!! I'm reading the Heartmath book on Anxiety.
my understanding is simply placing your focus on your heart center and breathing in and out as if it were through your heart center creates coherence. I'm really curious on this topic too bc when I do it, I actually feel cool energy in my heart... Kind of similar to reiki and I was curious if this happens for anyone else?
