To sum it up, my impression is so far that grasping/identifying as the khandas is what gives rise to a whole host of different speculative views on the self and on the world.
It seems that maybe MN 22 is suffering from a copying error; the eternalist view isn’t itself a ground for views, it’s just a wrong view that isn’t explicitly formulated in terms of the khandas, that arises from grapsing the khandas. So maybe MN 22 got a bit jumbled up somehow.
