Is kundalini awakening a requisit to Harvest?

[Infinite]

Yes.

Kundalini awakening is the same thing as becoming harvestable to any plane of existence.

It is the exact same phenomenon as polarizing. The more polarized you become, the higher the kundalini serpent has stretched. 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).

All spiritual development is the height at which the inner and outer vibratory understanding has reached its meeting point in the magnetic spiritual energy field.

Thanks for your reply. This regard to STS entities too?
