Note:  There is another Chinese man who is called
Lu Tsu, a Daoist, who is reputed to have written
the book

lived at roughly the same time, but character for
his surname
Lu is different--most likely these are
two separate and different people.

When the monk asked Roso "What is meant by
`in front of your nose'?"  Roso responded,
"Slender bamboos cannot be used as musical
instruments; a gourd cannot return to the trellis it
grew on."

He is saying, in a very metaphorical way...

"Slender bamboos cannot be used as musical
instruments, and a gourd cannot return to the
trellis it grew on"

...he is saying that you have to move inwards,
just watching that you are going directly and
straightforward in front of your nose. Don't go
zigzag. The inner world is vast; don't go here and
there, you will be lost.

Hence, I have been telling you, "Go like an arrow,
direct." Hit the source, and everything else
becomes so clear that one who has hit his center
never asks a question again. All questions are
dead, all answers are dead; you have found the
golden master key...
