Is kundalini awakening a requisit to Harvest?

[anagogy]

But if the majority of Wanderers aren't aware they are Wanderers, doesn't that mean that they are inactivated and will have to repeat third density??

No, because they are just "acting" like 3rd density beings. After they die, they, take off their costume and resume their normal configuration. They volunteer for 3rd density DNA connections with their mind/body/spirit complex. A normal 3rd density soul isn't pretending. It is what it is. The spirit complex of a wanderer is not really what it pretends to be, but enough negative karma can "trap" them here.
