A Partial Answer:
I'm rather new to puzzling, so these are some of the first things that popped into my head:
When sorted by comma, the sets of words grouped together creat this:
n at er A m se i u on and on go u a and x to co ly for x
Counts key old handphon secret you so puzzling go great powerful the dear do greater big not brings secret coming important
I tried ceaser cyphering the first grouping, but no luck
When sorting the second words alphabetically I get this
A a and and at co er for go i ly m n on on se to u u x x
handphon
do great greater key brings old coming the so secret secret counts go powerful you not puzzling dear big important
When sorting the first words alphabetically I get this:
x co for n u a and and on A c at to er on u ly m i go se
big brings coming counts dear do great greater go handphon important key not old powerful puzzling secret secret so the you
A couple of interesting things I noted:
There are 36 clauses (A nice perfect square)
secret is the only word repeated in the first "section" of the clause
a, and, on, u, and x, are all repeated in the second "section" of the clause
handphon is the only non-word in the first "section" of the clause, the only clause with a capital second "section", and the only clause separated by a line break. I have a feeling this is a big part of the riddle.
there are 21 clauses total. 12 in the first paragraph, and 9 in the second
Those are my observations! Hopefully someone with more expierence than I can do something with them
