Hi Alexander,
categorizing various aspects of spiritual practice or attainments is always interesting. Even though it is all theory it reveals certain aspects of what we call human life. I think your list has good foundation. Just need to add more categories. For example, there exists the type of followers that are somewhere between dogmatic and mystic. They tend to focus on qualities such as kindness and compassion for others. They typically are not hardcore about doctrine. But at the same time they are too focused on worldy life rather than going beyond as mystics.
hm we would probably put them somewhere in #3, but they have not followed the life-path yet. so, the potential lies dormant. but they are not falling prey to the failings of superstition, nor falling into intolerance and persecution like happens to the dogmatic. they intuitively understand the perennial thesis, but need to follow it for it to reach its full conclusion
note these aren't "rankings" like streamwinner, nonreturner, etc, but rather sociological categories.
I wrote this as part of a graduate course I am doing on religions. This week I am doing a chapter on Indian religions. I might publish the whole collection when it's done (a month or two). It would a very academic read, but could be useful
