The time is moving by 
Like spurs of sliver threads 
Opening its deep sky 
With many gleaming beads 
The lots of Incidental Stars 
In light oceans faraway 
Time's yesteryears scars 
Before coming of the day 
 
Hold on to what you know 
For nothing is for certain 
This stage is just a show 
To draw up a later curtain 
We see the same afternoon 
Before it leaves here on 
The dark site of the moon 
Never into sight then drawn 
 
What slips between the two?  
The sense and knowledge give 
Are we seeing clearly through?  
Or can't we that great relive 
What’s outside there invisible?  
From the exposed human eye 
Into too many realities divisible 
And each one to each - apply
