Time: 45 minutes.

Situation: A quiet room with my eyes closed, sitting Burmese-style with my hands on my knees.

Experience: I was excited and a little nervous going into this session - new territory. I closed my eyes and immediately perceived my visual field "vibrating" at about six to eight times per second. Concentration was high. "Vibrations" were so fine they were difficult to see well. I resolved to pay very close attention. Awareness shifted to my sense of touch and the "vibrations" sped-up to maybe twelve times per second or so. I slipped into a little story and snapped back. Concentration was higher. "Formations" were evident evident, but it was more the vibratory nature of reality that was the object, not "formations" themselves. Background mental process were objects. There was a persistent desire to "see if I can make that weird-thing that happened yesterday happen again." This desire was data in the sense-field. Equanimity was high. The distinction between arising and passing was clearly evident. Awareness was sucked into nothingness as if into a vacuum, momentarily it reemerged. The "Door", appeared to be Impermanence, and there was was a physical wave of pleasure. I was back to square one. This cycle repeated several times, with each cycle going going faster and faster, always with the "Door" of Impermanence. "Vibrations" were going FAST. The "Immaterial Jhanas" cropped up now and then but I stayed focused on vibratory nature of reality. After a few of these cycles, the thing that happened yesterday happened again: 

My head began to tingle around the middle of my forehead. The tingling sensation slowly migrated to the crown of my head. There was a sensation like something cool and bubbly was gushing out of the top of my head and down the sides of my head and face. Space was subtly luminous and had a three dimensional quality (similar to Boundless Space, but different). There was a mellow and pervasive physical pleasure in the body. I felt joy. Reality was was still vibrating - even this state arose and passed, was not me, and was not satisfying - but it was pretty nice, don't get me wrong. Continued attention on the vibratory nature of this state was probably the reason I dropped out of it and into a place of equanimity and slower, more jarring vibrations. I continued to pay attention to the vibrations, they got finer, there was a tingling sensation around the middle of my forehead . . . and after a bit I was back in the luminous, physically rapturous, joyous space again. Continued attention to the vibratory nature of this state had me drop out again, and the session ended. It felt like I'd been meditating for five or ten minutes . . . not the forty-five I actually had been.

Observations: Lets see what the boys and girls on the "DhO" have to say.
