One thing that I learned from this forum, and more specifically from Jeffrey was the idea that I need to own my meditation.
That is, nobody can tell me what I need to be doing.
Of course, I'm responsive to advice and I do buy in to the whole system of jhanas as they are presented here. Otherwise, I would not be here.
However, for the longest time, each meditation session had this pall of judgment over it where I wondered if I was "doing it right". Now I have the feeling that I this though, in itself, is harmful to the experience.
Thus, now, when I meditate, I do it how I like to do it.
Two statements allowed for this lightbulb to come on. The first was when Jeffrey asked me if I "enjoyed my meditation experience". The answer is, sometimes yes, sometimes, no.
This made me realize that I should always enjoy my experience. Or at least make it as enjoyable as possible. There are a number of ways to do this, and I think most of us have heard them all ready, but I just want to say that now, I, too, am a believer.
Also, Jeffrey spoke about some meditation groups "turning meditation into self-torture." This made me realize that, I, too, was guilty of this sometimes and have now stopped. My meditation sessions are much better now.
Finally, during the retreat, Zach told me, "I have to do so many things other people's ways in the rest of my life; I'm going to my meditation my own way."
Me, too.
I can't say much more or elaborate this idea further at this point.
Once I have written it down, it seems a bit obvious and even trite.
But it had a profoundly helpful impact on how I practice.
