If you want to write haiku by your own:
3 lines: The first has 5 syllables, the second 7 and the third 5.
Or a total of 17 syllables.
For a 'tanka' you add two lines of 7 syllables in each line.
The poem should have an element of nature. Try it!
It works best after meditation.
If you have a question or any comment, don't hesitate to write to me.
