is a very short form of Japanese poetry typically characterized by three lines. The essence  of haiku is 'cutting' - this is often represented by juxtaposition of two images or ideas and a 'cutting' word or 'cutting' phrase between them. Normally, haiku is about landscape experience in connection with a deep emotional or cognitive insight.

snow -

white on black

your delicate shadow is walking ahead

even on this grey day -

the world's winter every-day

has its pleasure quarter

from my window:

snow covered the old graves -

nothing remains

this form dissolves -

there is nothing

i can see

cold night ahead -

the lights are far away -

the moon is near to the blue horizon

the path is gliding in the night

the blue horizon passes into dark -

the moon is gone

from the last year

just a tiny shadow  -

your smile in my memory
