Sirius

Sirius,
Always half never whole.

The Dog-Star,
Two stars,
Bright,
Locked in a dance for eternity.
Once half now whole.

Always half
Never whole
Always reaching
Never to a goal

Starlight,
Star bright,
First star
I see tonight

One is king
One is queen
But which is which
And who is seen?

Brother brother
Turn and turn
Will he leave?
When will he learn?

Turn turn
And turn again
You see the what
But never the when (end?)

Half is whole
But with his friend
And thus did Johnathan
Meet his end.

Who is John
And who is David?
Who is king?
Always half
Never whole

In the end,
There can only be Cain.
