for the first time (again) Last night during meditation and samyama I saw clearly how that sleepiness which isn't really sleep is entering Samadhi. Previously I had my doubts, it just seemed a lot like a nap from which it was hard to awaken.
I got a little headache at the end of my session, at least my body told me it was a headache, but when my attention went to it in a certain way, I could feel myself slipping into an altered state consistent with a Samadhi I experienced using a different method. I kept slipping in and out. It was like the headache was a door to something else. The electrical/buzzy quality was clearly there and for the first time since starting AYP I was Aware in that state. This is encouraging.
