Why exactly do negatives entities inevitably need to switch polarities?

[Minyatur]

You can't so much rise above the illusions while wanting to remain caught up in them.

Both paths need to be transcended, as there is no many.

In sixth density, the density of unity, the positive and negative paths must needs take in each other for all now must be seen as love/light and light/love. This is not difficult for the positive polarity, which sends love and light to all other-selves. It is difficult enough for service-to-self polarized entities that at some point the negative polarity is abandoned.

I liken having transcended polarity as to be alike the Logos. You have no selful polarity, you encompass both the potential for positive polarity and negative polarity as they come to manifest. So it is not only the negative path that is forsaken, the positive one is transformed also from what it was as it takes in the negative polarity. The Earth blinks at neither the chirping birds or the hungry wolves, that is unity.

Polarity itself is a principle of separation.
