Huh, those brain stimulation methods might actually be practical to use now, thanks for mentioning them!
Regarding skepticism of survey-data: If you’re imagining it’s only an end-of-the-retreat survey which asks “did you experience the jhana?”, then yeah, I’ll be skeptical too. But my understanding is that everyone has several meetings w/ instructors where a not-true-jhana/social-lie wouldn’t hold up against scrutiny.
I can ask during my online retreat w/ them in a couple months.
How do you work w/ sleep consolidation?
Sleep consolidation/ “sleeping on it” is when you struggle w/ [learning a piano piece], sleep on it, and then you’re suddenly much better at it the next day!
This has happened to me for piano, dance, math concepts, video games, & rock climbing, but it varies in effectiveness. Why? Is it:
Duration of struggling activity
Amount of attention paid to activity
Having a frustrating experience
Time of day (e.g. right before sleep)
My current guess is a mix of all four. But I’m unsure if you [practice piano] in the morning, you’ll need to remind yourself about the experience before you fall asleep, also implying that you can only really consolidate 1 thing a day.
The decision relevance for me is I tend to procrastinate heavy maths paper, but it might be more efficient to spend 20 min for 3 days actually trying to understand it, sleep on it, then spend 1 hour in 1 day. This would be neat because it’s easier for me to convince myself to really struggle w/ a hard topic for [20] minutes, knowing I’m getting an equivalent [40] minutes if I sleep on it.
