How then does a single person achieve Amaranth?
Didn't you say Amaranth was a state of existence where multiple people achieved CHIM?
A single person doesn't achieve Amaranth. Neither do two people achieving CHIM in the same universe qualify as Amaranth. To have Amaranth, you need a New-Man (say, Vivec) creating his own universe, and then the people in that new universe also achieving CHIM. Lets see if http://img684.imageshack.us/img684/4435/zaeq.jpg helps.
Right. I thought Amaranth was making your own universe and having your creations achieve Amaranth also. You say otherwise, with CHIM being the former. But neither Vehk nor Talos seem to have their own universes.
I was using CHIM too broadly, my mistake. What was meat was the state that the Loveletter calls the final subgradient, Z, "individuals beyond all AE." CHIM is one way at that. We don't actually know if Vivec or Talos have their own universes, but I'd argue that if they don't it is because Amaranth is not [yet] their goal. The Loveletter does mention Vivec returning from the Aether (which is the Landfall, in my guesses), so that could tie in. Or maybe their state isn't equivalent to the New Man of the Loveletter. I don't think we (or at least I) fully know this issue yet.
There's another post by MK about Amaranth in TIL's archives, btw:
don't forget the Amaranth. There *is* one step beyond CHIM, but you're right in that it is not godhood. It's the flowering of a statehood where the images you give birth to in your dream-- stolen (?) from first dreamer-- wakes up. Wails knowing free will. And begins to dream in the same way. Children of liberty without end, and then the music lives forever as a pirate radio tuned against the rules of Heaven and the vulgarities of Hell.
I'm off for the night, hopefully I've not completely confused everything again
