Pang Yun was a famous lay practitioner in the Chan school of Chinese Buddhism.
He displayed the extraordinary potential for us all to be truly awake in the midst of the world.
Here is a lovely tale of Pang Yun's encounter with a master, and his ensuing realization experience.
When he came to Baso he again said, 'Who is he that is independent of all things?'
Baso said, 'When you have drunk all the water in the Yang-tze river, I will tell you.'
At this, Koji underwent his great experience and composed another verse:
(Two Zen Classics 263)
Well versed in the Buddha way,
I go the non-Way
Without abandoning my
Ordinary person's affairs.
The conditioned and
All are flowers in the sky.
Nameless and formless,
I leave birth-and-death.
P'ang Yün (龐蘊 Hõ Un)
