Is kundalini awakening a requisit to Harvest?

[kristina]

Yes.
...
4th density harvest is simply when the kundalini serpent has reached the heart chakra or energy center (and become seated there more or less stably).

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??

Yes. If you are not enlightened or asleep within the forgetting, none of us can remember who we are or why we came. I feel as we take our experiences one step further up the energy centers we are becoming more and more awakened/enlightened with each advance upward toward the sixth chakra. And for a Wanderer who is sleeping, this would have to be more than just self realized (3rd enerygy center) but be able to at least apply universal love and understanding (4th energy) to each experience before they would be harvestable.
Wanderers are not exempt from repeating due to being spiritually asleep.
