Several people asked about what kind of meditation I am doing. I'm doing a version of Kriya Yoga. You can find an explanation of the whole thing one the download page of the Kriya Yoga site of Ennio Nimis. In particular, I am focusing mostly on Maha Mudra and Kriya Pranayama which are pages 106-108 in section 2. The diagram on page 104 shows the path that your focus should take up and down your spine. I'm also taking random teachings about meditation that I've read in the past to try to keep my focus and fade out the chatter of my loose thoughts.
I'm still quite a beginner, but I'm excited by my gradual progress. It has become a very important part of my morning ritual and only takes 20 minutes or so including the stretching.
