Reddit mentions of Moon in a Dewdrop

I found it on Amazon, you can "Look Inside" the book and find it on page 5-6: http://www.amazon.com/Moon-Dewdrop-Writings-Master-Dogen/dp/086547186X

"Rujing was a priest of the Caodong School of Zen. Although he had inherited and renowned master Daokai's brocade robe, he never wore it or any robe with woven patterns. He forbade his students to be intimate with kings and ministers. Rujing denied the view, conventional in his time, that each of the "Five Schools of Zen" had its own teaching. He called the taching he was transmitting "the great way of all buddhas" and even disagreed with those who called it the Zen School. Rujing also denied the widely held definition of Zen teaching as a "separate transmission outside the scriptures." He said the great way is not concerned with inside or outside."

It is inside of this book of his writings: Moon in a Dewdrop

Be careful though, if you read it you might end up being a green mountain walking ;)

Some good books about Zen, if you're interested in learning more:

Hardcore Zen: Punk Rock, Monster Movies and the Truth About Reality Great book, written by a modern Zen 'master.' Colloquial, not translated and thus easy for us westerners to understand.

Not Always So, Shunryu Suzuki

Moon In A Dewdrop, Dogen This guy is the real shit. Lived hundreds of years ago. You can go as deep as you want into this guy's writings, many levels of meaning (or none?). More metaphorical/figurative than the others, very poetic.

When/if you read this stuff, don't worry about understanding everything sentence. It's easy to get caught in the trap of reading and re-reading sentences and paragraphs to try to understand, but in doing so you miss out on the flow/stream of consciousness of the works. Just read it through, eventually the ideas will start to become clear.
