How do you envision fourth density?

[Aion]

There is a difference between "the Veil" and this notion of "knowing everything", I feel.

Yes, there are still mysteries in 4D, but no it is not 'veiled' in the same manner as Third Density.

The polarization process, as it enters fourth density, is one which occurs with full knowledge of the veiling process which has taken place in third density. This veiling process is that which is a portion of the third-density experience.
