NuanceOfSuchness, thank you very much for sharing your experiences during your practice with us, even as it was used to add more details in your questions.
I have enjoyed having a new participant in this forum, sharing jhanic and meditative experiences with us, which frankly to me would be out of my league at least for the foreseeable future.
Would you be so kind and helpful as to act as a kind of teacher to me, while I sincerely hope that my questions may help you even if only for a bit?
First of all, I think Lal has mentioned somewhere that lobha, dosa and moha are gradually reduced and eventually eliminated as one gains insight into anicca, dukkha and anatta.
You mentioned that you perceived the insignificance and insubstantiality of dhammas. This seems to be what anatta is about.
If I may ask, after that experience, do you feel less attached to sense pleasures and/or less repulsed by phenomena that normally seems unattractive or unpleasant?
What about internal dhammas? Do you find yourself being less attached to notions of an unchanging, substantial self? If you go deeper, do you realize experientially that rupa, vedana, sanna, sankhara and vinnana are insubstantial, ever changing processes that can undergo unexpected change and dissolution, which offer no real refuge from dukkha?
What if you stayed with these observations and realizations a while longer and more frequently in your practice? Would it deepen the quality of your practice as well as your daily life?
I eagerly wait to learn from you about your progress, for such things interest me greatly and I would be glad to be of whatever little help I can provide, assuming that I am helpful at all.
