In thinking about ways to present the aqal model here in our green tinted community, I have found some nice and fuzzy (nonthreathening) language.
So instead of levels and stages of development, we can say widening circles and turns of the spiral. Each widening circle is more inclusive and embraces more. And level five is then the fifth turn of the spiral.
And in talking about the different turns of the spiral, we can emphasize the gifts of each. The gifts of red, amber, orange, green and so on, and how we each can - and do - access and use the gifts of each, at least those within our current embrace. It is similar to having access to many paint buckets, using the different colors according to what the situation seems to call for.
Instead of being hierarchical and threatening, it becomes fun, embracing, spirally and colorful (!)
Hopefully without being less accurate.
