I really like HRV philosophy and techniques, I had a wonderful seminar about it a few years ago, although I haven't worked with the device. This is a lovely post, thank you for sharing! Acting by the heart and not by mind is one of the key factors, open hearts and re-learn all these things that we knew but society and "schools" forced us to forget... An interesting process for sure! Wonderful that you have found a way that works for you and keeping your balance!
