Choosing to maintain illusion

[Siren]

And is it desirable to work toward ending the illusion? I feel the illusion persists at least through 4th density (which Daddy Ra says a denser illusion).

Yes, 4D is a denser illusion, as Ra described. Denser illusion means more lucid, vibrant, more packed, fuller of light. The illusion, or rather, the Grand Illusion, was created by the Logos. Each vibratory spectra (or density) is an illusion and the entire Creation is the Grand Illusion through which we experience the experience.
