Hi Dodge,
What I usually do is get to 4th Jhana and insight (vipassana) whilst in 4th Jhana. I usually note sensations and phenomena I see. Off the cushion, I note, notice and contemplate as a mix according to how much attention i have to give to my job at any given time. So vipassana is going on (If thats what you mean) but my experience in meditation is very much wrapped up in Jhanas.
After that first experience, I found it difficult to concentrate in meditation for a couple of weeks after that. I have not really had the intensity of DN experiences that many describe on this website beyond feeling melancholy or irritable for a day occasionally (which is not normal for me) so presume that its bleed through from practice but only occasionally had really troubled meditations
You are right, whatever the case, I need to keep practicing and moving forward.
I haven't been keeping a regular practice log here since you are one of the few who respond to any questions I have. I have a log on KFD which I have been keeping up to date. Thanks for your advice and hope your practice is going well
