I'm going to make a comment now...........oops too late. I'll do it now..damn! not fast enough. I'll do it(comment) NOW....ha! I beat it to the punch. All jokes aside too many live in the regret of the past and fear of the future.An enjoyable read...................scribbler

A few thoughts:

Stanza 2:
*for it dies as -- I feel like this line wants finality rather than flow. Maybe: for it dies. (stop)/Each new moment . . .
*I am neither then nor when -- I have mixed feelings about putting this at the end of the stanza. Part of me wants it at the beginning because the line "turns to then" was a stumbler for me initially, until I read this one.

I know this is freeform but wonder what you'd think of some symmetry, e.g.,

I am not made of past
for it dies.
Each new moment
turns to then,
I am not future,
nebulous,
undreamed of
I am neither then nor when

Stanza 3:
*I am right now, -- "Right now" seems a little weak. This line seems to call for more punch, e.g., "I am now"
*immediate in present, -- Again, I think this could be punchier without "in"
*before, bright chaos undefiled by choice... -- Just commentary here. I find the use of "defiled" interesting. I never really think of my choices as defiling. Defiling what? Infinity?

Stanza 4:
I am the now,
the point of highest amplitude.

I think this is a great ending and I thought the cresting wave image was very appropriate.

Jim,

I have read the comments already supplied and feel they have pretty much covered the potential changes that would turn this from 'good' to 'exceptional'.

Existance - is normally spelt 'existence'...unless this is an American spelling, although my American spellchecker doesn't recognise your spelling.

Would the first line still work like this:

Each instance of existence.

I did enjoy this write and really liked the final two lines.

regards,

HS
