Qabalah and the Law of One.

[Henosis]

I would relate Tiferet to 4th density, Gevurah and Chesed to the 5th,  Daath to 6th, with Binah and Chokmah related to the 7th.

Kether I would equate with the 8th, the Logos or the Divine Will.

What about for 1st, 2nd, and 3rd density?

I agree with OP interpretation of 1st being Malkuth, 2nd being Yesod, and 3rd being Hod/Netzach.

If you look at the picture in the OP with the lightning flash... if you follow the flash, I see the densities being basically equivalent with each angle change of the lightning, with the exception of the line of 8th density. I think this line would best represent the completion aspect of 7th density and the merging with the Logos/Creator.

Just FYI anagogy....I wrote you a MASSIVE reply yesterday that I pondered for about 15 hours about how it would appear at first glance based on Ra concepts that understanding/wisdom (binah/chokmah) would represent 6th density and the blending of love/wisdom....but upon further analysis this is likely incorrect...but then I re-read everything and said nah forget it haha. I'm kinda mad at myself.
