I believe you are referring to:
ã»ã¨ã¨ãŽã™æ¶ˆãˆè¡Œã方や島一ã¤
hototogisu kieyuku kata ya shima hitotsu.
(summer) little cuckoo. it disappears. a single island
The "Zen influence" can be found on two levels:
1. It is not so much in the words themselves, but in the experience it describes.
2. Buddhist terms with the same pronunciation as some key words in the poem.
#1 is impossible to explain, it must be experienced.
As for #2:
hototogisu is a "season-word", something that is included in almost all haiku and hokku (this poem is a hokku). This particular season word is a species of bird, but indirectly refers to the summer.
ho is also the pronunciation for the Buddhist Teachings, 法
toto also means "attainer of perfection" 度得
gisu also means "pillar", or "center", å®—
shima also means "that which is derived", i.e. interpreted/analyzed, æžæœ«
You could therefore also hear the poem as:
Attaining the perfect core of the Buddha's Teachings - it disappears - all separation becomes one.
The poem itself is a reference to a much older poem found in the Kokinshū (#409).
It is Basho's brother
Listen to Basho.
Basho is in the small hut on the water who offers you the haiku. First, for him to be revealed to you, you have to win the Sumo-Wrestler match.
You don't need to worry about that.
Basho is actually the "old poet" who lives in the lake house (far left of the island). He will fool you by saying Basho is in the village. Pick up the mortar from the lake, and the rotten fish from the Fortress steps (you have to climb up there to find out about Basho in the first place). Take the five challenges in Edo and the Bridge, and Basho will find you when you win the Sumo match. Follow him back to the lake to begin your Ninja training. (see related question)
he's in the hut all the way to the left of the island
You get the ninja bag from Basho, the ninja master.
When you do all of that stuff you earn the claws from Basho
To get Basho to help, you must perform a bunch of good deeds around the island. Like helping the blind woman with her trees. He will appear after the sumo Wrestling match. Hope that helps!
you have to train with basho ang show you are ready to keep them
we have to go to the man who told us about basho buying
you need to get train by basho to do ll that stuff
