I'm going to collect any links and postings by others that I find on the internet to do with the progress of insight (Ñanas) and collect them here in this post as they come up. I'll start with a great modern description of the progress of insight without all the technical language by Shagrol at the DhO. Below his descriptions are links to more descriptions of the progress of insight, the stages and knowledges that one may come across when practising Vipassana meditation. Feel free to add any links in the comment section that I've missed and I'll add them to the list.

Basically, it’s the old unpeeling the onion metaphor. There are layers and layers of identification, but a finite number.

If someone steps out of the trance of normal discursive thinking about their life, the first thing they notice is that they have thoughts and sensations in their body. Mind and body.

If someone investigates mind and body, they will see that they influence each other. Cause and effect.

If someone investigates cause and effect, they will see that we are most of what we do is actually driven by a visceral reaction to the unsatisfactory aspects of experience. Three characteristics.

If someone investigates the visceral reactions to the three characteristics, they see how these reactions are like dominoes hitting one, then the other, then the other. Arising and passing. When they can simply watch all that happen, the body might have a small taste of the space between the dominoes. Arising and passing event.
At this point, meditation is a comedy of errors, which comes from trying to “not see” what is actually happening. It’s a more detailed map because this is where people really need help.

Instinctually and somewhat unconsciously, the person will try to “find” the spiritual experiences of the A&P the nothingness of the A&P event. They don’t find it, and instead it feels like everything good is slipping away. If they actually just watch that happen, then they get the insight into the nature of dissolution: things don’t stick around.

Instinctually and somewhat unconsciously, the person will have a sense of loss of control and be surprised by something, which evokes primal terror. If they don’t see fear as an experience in awareness, then the meditator gets lost in thinking about all the things that evoke fear. If they actually just watch that happen, then they get the insight into the nature of fear. Surprise is surprise — no big deal. And even fear is fear — no big deal.

Instinctually and somewhat unconsciously, the person will want to protect themselves from surprises and will instinctually create an ongoing, low-level sense of misery to fill up the space. It’s a coping mechanism. But if the person sees misery as misery, then they get the insight into the nature of misery.

Likewise with disgust. Long term misery feels awful. Disgust is an empowering coping mechanism that allows someone to feel more in control and more powerful. “I am disgusted!” But if the person sees disgust as disgust, then they get the insight into the nature of disgust.

Likewise with desire for deliverance. The person is somewhat empowered and thinks, “There must be a way out of this.” There is a focus on problem solving, perfecting practice, finding better teachers, etc. It has the flavor of some confidence and passionate seeking. But if the person see this as another reactive pattern, then they get the insight into the nature of desire for deliverance.
Likewise with re-observation. The person is now re-observing everything they went through, all the strategies, all the attempts to find the experience they think will make them happy. It has the flavor of desperation and failure. If they see this desperate feeling of “nothing works” as just another reactive pattern, then they get the insight into the nature of re-observation.

Low equanimity is finally realizing that fighting experience or trying to find a difference experience other that what is actually happening is impossible.
High equanimity is being mostly at peace with this and continuing to sit, mildly curious about [questions such as]: “If all of these experiences occur within awareness, then what is awareness? What is mind? What is knowing?”
Stream-entry happens when the pervasive non-reactivity of equanimity (not grabbing at objects, not searching for objects) allows for momentary non-grabbing. The meditator doesn’t “do” anything. It’s like when a sun runs out of fuel, and it collapses into itself.
