...The suttas say that sariputta attains boundless space by discerning all objects and finding there causes and hence discovering the way out which agrees with this approach....
Feel free to ignore my post since I'm relatively new to Buddhism and a rank amateur in Buddhist meditation
If I may, the process you describe sounds something similar to one I did years ago, before coming to Buddhism. I believe Tilt is alluding to how Buddhist practices would see it - he didn't give enough information for me to be sure. Maybe one of the others could give clearer comparison because I shouldn't be teaching - you'd be listening to an amateur.
I can feel free to comment on what I once did, however. In my pre-Buddhist experience, I encountered a spacious mind that sounds similar. For me, the noting of each thing, then spacious "element" felt like an alternate reality. I decided that this was the phenominal flux that is described by some philosophers, shamen, etc. "Things," and "points in space," became only reference points after a while. I decided that one could experience the flux directly and it was a rather pleasant experience. It felt like an alternate reality.
Over time, though I began to question whether I had "found something" or whether I was creating the state. Kind of like a guided meditation or a guided imagery can be generated, had I generated something I called a different reality, or different glimpse of reality at least. That's the kind of question I think any seeker asks his/her self from time to time. Am I finding what I'm looking for? Or am I on a side path? IMHO everyone makes that decision each moment. They do what they believe, or are trying to study. I ended up here, which tells you I am still looking for something.
So in a Theravadin forum, I expect some views to be far away from mine, some close to mine, but they are all views. Views are like noses, everybody's got one. Other body parts get you in trouble on a public forum
OK (drum roll).....my take on Sariputta
After doing something similar to what we did (naturally), he saw that it wasn't a method for attaining - it was a wisdom to be learned and experienced. All things are like "this."
