If we are Infinity

[godwide_void]

In my perspective 3rd density entities who are not ready for 4D will incarnate in other 3rd density worlds which will provide the lessons they need to learn before entering any 4th density planet.

This is entirely true, although what I was referring to were dual activated 3rd density/4th density beings and harvestable 3rd density beings. 3rd density beings who do not meet the criteria for immediate 4th density incarnation following bio-termination will, as you said, undergo another cycle of 3rd density upon another planet which currently supports an environment whose dimensional infrastructure is of the 3rd density in order to refine themselves via the lessons and catalyst available therein.
