Negative polarity.

[Ashim]

Unlike most of his "family" a 6th density negative wanderer would be aware of the method of negative harvest.
The higher self would inform the entity, setting up the conditions required.

I have often wondered about the 95% and feel that it must be a combination of 2 factors.

The entity must generate an intention to separate, a force of intense repulsion, amongst all the beings it interacts with. To be someone you would NEVER wish to encounter again. A small percentage of residual beings would however remain, this is important.
These entities would be willing to enter a further incarnation within the negative adepts universe solely for the purpose of being able to cause suffering, kill and act out their revenge on this being. It would be a negative attraction. Hence the 3 way split at harvest.

The unpolarized of under 95% negativity would repeat part of the 3rd density cycle on another 3rd density planet, like Tau Ceti E.
The positives graduate to Earth 4d positive with the negs creating their 4d negative world and opportunity to work off their "bad karma".
