Baizhang Huaihai was the direct heir and most famous
disciple of Mazu.  After leaving his master, he set up his
monastery at
Baizhang Temple in the high mountains of
Jiangxi Province, China.

Baizhang is reputed to have started the first monastic
rules of Chan, supposedly writing a treatise on the
particulars.  He is also known for having his monks all
work at the monastery, distancing the Chinese from the
Indian Buddhist tradition of begging for their livelihood--"A
day without work, is a day without food" is his well-known
dictum on this subject.

Baizhang's 1st teacher was a man named
Daozhi, who
gave him the dharma name
Huaihai.

To understand Hyakujo, the first thing is to
understand that enlightenment can only be
sudden. The preparation can be gradual, but the
illumination is going to be sudden. You can
prepare the ground for the seeds, but the
sprouts will come suddenly one day in the
morning; they don't come gradually. Existence
believes in suddenness. Nothing is gradual here,
although everything appears to be gradual; that
is our illusion...
