I am currently meditating thirty minutes per day. I wonder whether I should meditate an hour instead or meditate for thirty minutes twice.
Basically, I meditate on compassion and after thirty minutes I'm not generating much of anything. I just sit there moving about on my chair, wondering about the time, etc.
Does this saturation after thirty minutes occur because I have always meditated this amount of time before? Or is it because I'm just not ready yet? In other words, are we used to whatever amount of meditation we're usually doing?
If this is so, would it be better to just always try to sit an hour if I'm capable? Should I just meditate as long as I can sit, whatever the quality may be?
