Long time ago lived a Zen master called Ikkyu,
Who was renowned for his cleverness among other qualities.
When he was a teenager happened to break a precious teacup which was a favorite antique of his master.
After the incident,
Ikkyu was very worried about it.
Later on,
When he heard the footsteps of his master,
He quickly asked him,
Master,
Why do people have to die?
The old master replied,
Death is natural,
Everything has to die and has just so long to live.
Then our smart disciple brought out the shattered cup and said,
Master,
It was time for your cup to die.
