Losing Focus

In yoga this morning, it felt like everything was falling into place: my breathing, a mantra ( something unusual for me), my practice.  Then something  clicked, and it dawned on me how well it was all working!  I think I got excited or something.  It was as though the realization threw me off!  I kept trying to get back to my breath and mantra and regain my previous rhythm. The focus and ease returned intermittently but never to the same extent. Interestingly, my lingering feeling about the class, though, is my memory of the absolute high I felt when I realized  I was experiencing "meditation in motion."
