After realizing the intent of Zen, people in ancient times used to spend decades polishing themselves thoroughly in order to free themselves from compulsions of conditioning and habit.
This is called the work of maturation; the completion of maturation is called the attainment of unification.
- Muso Kokushi (1275-1351)
Heaven turns so slowly and gently,
It tolerates my age.
Without mercy,
Days and months advance to cut off my time.
I return to my cave in the mountain,
But the trees are all gone.
I look down on the river,
And all I see are meandering curves.
The sun is captured in a cage of delicate clouds.
I listen to the wind.
Suddenly I hear the Temple Bell!
The sound comes washing over me,
Waking me from the dusty labor of my thoughts.
And distant heaven opens wider and wider to me.
- Hsu Yun
