Memento Mori

Memento Mori
 
the great equalizer
of the final frontier - I'd chop these two lines and start with L3
        quiet as the hawks and harriers
        sent to carry our bones
        to the bed we have made -- I'm not convinced you need this either -- the "go to sleep" makes it a bit redundant and it's a little on the cliched side
(go to sleep and good night, -- you could cut "and" -- it's an aside so a few terse phrases will suit the idea
there is no need for mourning) -- "there is" doesn't really need to be there
 
the mute seraph
white stork -- I like the connection between seraph and stork but I think it could be stronger -- if you want them seen as one and the same thing, you might consider "in white stork form" or put your parentheses here (white stork) and take them off the later line.  Actually, I'd suggest that anyway -- a colon after Gaia, and no parentheses on "a biennial bairn".
stole your soul
gave you to Gaia
(a biennial bairn)
for her costume garden
 
the mathematicians
and realists and bankers
wonder if there is an art to dying
 
the zealots and Baptists
and Mormons are deifying -- perhaps just "deify" instead of "are deifying"
their casserole allegories -- like this!
 
the extent of language -
narrowed by the egotists -- a dash here would be beneficial, rather than on the preceding line
what can't be said
should be sung 
(when there aren't any words -- a comma here perhaps, and remove "then" on the next line
then we can just hum) -- I like parentheses, but they are being overused here. This isn't an aside, it's a main part of what you're saying
 
charging towards
the great mirage
(constructs of wishful wishing) -- whereas here they fit
assuming that space is vast enough
to hold our needs -- I'd probably tend to put a strophe break here as the next line seems a separate thought
night after night
we stare at stars
and wish away their
credibility
 
Capitalism-
our sacred puppeteer
selling the rights
to eternal life
(and acres on the moon, too)
the rich are buying their
legacies with life insurance
policies -- this strophe, while containing some good phrases, seems out of place in this poem.  It changes the tone to preachy and that's jarring.  Personally I'd remove it and set it aside for another poem.
 
Poe inspired poets lie
awake in the rustling night
dreaming of dying,
and romanticize lying
in her sepulchre -- her?
there by the sea
 
but as is our arrival - -- your dashes are becoming dashed difficult to deal with, and decidedly Dickinsonian...
we depart without
station.
to go (or not go)
somewhere (or nowhere)
captivated (still)
by our own (unassuming)
impression -- you could halve your parenthetical elements and not lose anything. Unfortunately, the sheer volume of them is detracting from the power of your closing statements

*When I finished my critique I read ellajam's and noticed a lot of similarities, so those are the areas I'd suggest you focus on first.  There is a good poem here that just needs some trimming and a good bit of polish.
