Meditation is not good or bad these days but a regular practice. It's a 'putting things in order' kind of experience. Cross my legs, stretch out my spine, overlap my hands, close my eyes and focus on my breathing. From there I focus on my internal state which is usually darting around. Little internal movies consume my entire attention. While these movies playback I often forget I am even meditating. Then slowly I fade further into the background and realize what just happened. "Interesting, so that is consuming my attention". I accept it. Each time I accept things I fade further into the background. The volume of self turns down, my mind becomes quieter. I don't need to think. I don't need an active mind.
I found my breathing was shallow in this session. Adjusting that became a focus point. Putting my breathing in order. I think I understand the premise of those stacked rocks/pebbles often associated with Zen imagery. When you sit in meditation/zazen you slowly start ordering and stabilizing things one element at a time, working your way up. Once everything is ordered/stacked. You try to stay in that state and see what happens.
