Elders and Stages

Vincent Horn has two posts worth checking. From "The Spiritual Map of the Elders":

Every map that describes the territory of awakening will have its strengths and weaknesses. Maps, in general, are only as good as the map-makers who’ve made them. They are also only, and always, mental representations of a place which one must explore for themselves. No amount of studying an idea about what a place will be like, or even studying what the path to that place will be like, can replace the actual journey. That being said, if one is going to take the journey to enlightenment, having a good map can do wonders!

A good map can point out the quickest route to your destination. It can also give you vivid descriptions of the landmarks along the way—and perhaps most importantly the pitfalls you may face. Knowing the landmarks along the route to enlightenment, especially when they are reached, provides a tremendous boost of faith & commitment to the journey itself. Also, having an idea of what obstacles one might encounter, and when these might arise, can save the spiritual practitioner years of confusion and stuckness. And in many cases it can keep one from falling off the path altogether. Good maps, again, are absolutely crucial with respect to making the daunting journey toward awakening.

From "The Stages of Enlightenment - A Revised Version":

The original model, created during the time of the Buddha and expanded since, described four progressive stages leading to the attainment of Arhantship. One who reaches the first stage was called a stream-winner (sotapanna), one who reaches the second stage a once-returner (sakadagami), one who reaches the third stage a non-returner (anagami), and finally there is the 4th stage, the arhant. Traditionally these designations were referring to re-birth, and the number of lifetimes that it would take to attain the 4th and final stage. They were also described in terms of various fetters that kept one stuck to the wheel of samsara. The 1st stage was said to cut 3 of 10 fetters (skeptical doubt, attachment to rites and rituals, and personality belief), the 2nd stage was said to weaken the 4th & 5th fetters (greed and hatred), and the 3rd stage was said to eliminate these two fetters. The last stage was said to cut the remaining 5 fetters (attachment to the first 4 jhanas, attachment to the formless jhanas, restlessness and worry, conceit, and the last veil of unknowing).

But don’t worry too much about the fetter-model as I’m going to largely ignore it in favor of Daniel Ingram’s revised 4-stage model. Ingram takes the same 4 stages but describes them much more in terms of how one’s perception changes, what the fundamental insights are, and the relationship to the diminishment of duality. He gets rid of the dogma surrounding certain emotional capacities completely disappearing as a result of enlightenment—what he calls the limited emotional-range models—and instead opts for a less dogmatic and more pragmatic understanding of these models. There is still quite a bit of overlap, and one can see how these two different models relate. That being said, if you’re a big fan of the original Theravada dogma, you may not be interested in reading any further. If instead, you’re interested in having an empowering, realistic, and achievable model of enlightenment, then keep on reading.
