I understand! I get the same feeling doing Tai Chi - I LOVE it! And there really isn't a way to express it in words, is there? I remember going through my routine in a moonlit room, with a soft, warm Spring breeze blowing peeper song through the open window. My mind and body locked onto a small portion of the workout, and everything just fell into place, melting into an absolutely amazing experience. I know that sounds weird and fake, but it's not. It was one of the most "real" experiences I've ever had. The only thing that has ever topped it was the overwhelming connection I felt when first holding my newborns.
This sounds amazing!!
