Then is Now.
Now was Then.
Now is Here

and will never be There,
for There will be another Now
and This Now will no longer be Here,

for it will have become Was
and what Was
can never again Be.

So, Be Then in the Now,
for it is the only Now you have
and the only Now you know,

the only Now that matters
before it too becomes a Now that Was
and will never again Be.
