Hey Jim,
Good to hear from you, I'm really glad you haven't clung to the anatta experience too and that you're still practicing. I know a lot of people from the L.U. forum and groups and, as you said, there is a tendency to think that the initial realization is 'it' although quite a few of them have gone on to see that there's still something to be 'done'. I reckon that the group itself will continue to develop and become more flexible, acknowledging the progressive nature of deepening insight as time goes on; they're doing a good thing but, just like this site, they'll change and progress but they're a good bunch all 'round.
Still sitting everyday (samatha mainly), using mindfulness as much as possible and going on the occasional retreat. Difficult for me to know where I'm 'at' (if anywhere). Jhana states come and go (rupa, not quite got into arupa), sometimes great joy / laughter, other times identification with suffering.
I've written a couple of
blog posts on jhana which seem to be quite useful in getting a hang of the basics, give it a read and see if there's anything helpful there.
I highly recommend trying to just be attentive/mindful of your immediate sensate experience as much as possible, e.g. look at how seeing doesn't involve anyone who "sees", even though you've seen through the illusion of a self there's still a lot of increasingly subtle sensations which continue to create a sense of subject - "you", an observer, an entity who sees - and object - anything which is not you, that which is seen. This can be applied to each sense door, even to thinking itself, so that you can see directly, just as you directly experienced not-self, how even the sense of an agent, a do-er, being, or any sense of even existing seperate from the rest of actuality is entirely imputed.
Thusness has these two stanzas which I've found to be incredibly useful to contemplate and see what they refer to experientially:
There is thinking, no thinker
There is hearing, no hearer
There is seeing, no seer
In thinking, just thoughts
In hearing, just sounds
In seeing, just forms, shapes and colors.

Congrats on your realizations so far, and thanks for the update. You could start a practice log on here, it's a really useful part of practice actually and you can learn a lot from getting input on the specifics of the techniques. Either way, good to hear from you and all the best!
