Why exactly do negatives entities inevitably need to switch polarities?

[kristina]

The defecting entity has to balance all the incoming terror and face it. It should be relatively easy for 6th unity conscious to choose this for one, for all. But it will hurt, si many refuse to look. So long as that is frozen, it is much like stockholme syndrome or child abuse catalonia.

However, having blocked heart chakra they need fast catalyst to regain balance. Like an addict, if they cannot get their fix of loosh, they may go back to what works. That isnt pretty. There is a channeled story of lucifer, heyl el being made to incarnate on earth.

There is an imbalance in creation. Fastest catalyst is this earth.

Why would the entity experience terror?
Why do you say they have blocked the heart chakra? I was under the impression that service to self, requires love of the self.

Heylel incarnated under the distortion of free will.
This was a very brave and commendable thing to do...from my perspective.
The entity was willing to be a placeholder for separation.
It was done with love. As is all.

Why do you say they have blocked the heart chakra? I was under the impression that service to self, requires love of the self.

"service to self" entity does not acknowledge love for other self and does not recognize worth of other selves therefore this entity is not accessing the green ray energy center and does not allow the energy to flow through it thus creating a blockage.
I only quoted the higher rays which you can read about the lower rays going to the higher rays starting at quote 15:12
here's your quote:

The center of heart, or green ray, is the center from which third-density beings may springboard, shall we say, towards infinite intelligence. Blockages in this area may manifest as difficulties in expressing what you may call universal love or compassion.

the blue ray...

The blue-ray center of energy streaming is the center which, for the first time, is outgoing as well as inpouring. Those blocked in this area may have difficulty in grasping the spirit/mind complexes of its own entity and further difficulty in expressing such understandings of self. Entities blocked in this area may have difficulties in accepting communication from other mind/body/spirit complexes.

Indigio Ray...

The next center is the pineal or indigo-ray center. Those blocked in this center may experience a lessening of the influx of intelligent energy due to manifestations which appear as unworthiness. This is that of which you spoke. As you can see, this is but one of many distortions due to the several points of energy influx into the mind/body/spirit complex. The indigo-ray balancing is quite central to the type of work which revolves about the spirit complex, which has its influx then into the transformation or transmutation of third density to fourth density, it being the energy center receiving the least-distorted outpourings of love/light from intelligent energy and having also the potential for the key to the gateway of intelligent infinity.
