From the Tang Song Period
 

Traveled to the end of the river,
Sat and watched the beginning of a cloud.
Occasionally I met the old man from next door,
We talked and laughed as if there were no tomorrow.

The transiency of time, the moment of here and now.
The most important theme about Zen is to live the 
moment as it is to the fullest.  


"Be in love with you life, 
Every minute of it."  Jack Kerouac
