Once up, on a Time

Once up on a Time, one must take care to balance well
Times are slippery things.
Once, up on a Time, I tilted oh-so-slightly
and found myself hanging upside-down
where nothing looked as it ought.
Gravity takes everything, even Times
(though they spiral down slow, if "down" is where they go
indeed), no matter where the balance lies.
But even if it's all the same (it isn't)
it's best to be careful. There was once a place,
up on a Time,
where, they say, just so, you could see forever
and not break your neck. Once. Still? I am unsure.
And it's not so easy, you know,
to get back up on a Time
that has once spun by.
