The densities as respects their sub-densities

[Lighthead]

This question is pretty much short and sweet. How do the sub-densities express themselves via their respective densities (the densities that they reside in)? For example, what would 3rd density, 6th sub-density be like? That example is hard to imagine for me because 6th density is the abandonment of polarities, and I would imagine that if you're in that late end of 3rd density, you're pretty close to being able to polarize. So it seems that the way some densities and sub-densities relate to each other is almost neutralizing if not paradoxical.
