According to my English dictionary haiku means: amusement in verse; Oxford Dictionaries differ slightly with: light verse, and add that it's a Japanese poem of seventeen syllables, in three lines of five-seven-five, traditionally evoking images of the natural world; and also that it can be a poem in English written in the form of a haiku. The great haiku master Basho died in 1694 at the age of fifty; it was common in those days to observe a few other rules of composition, which many of us have deliberately disregarded in the micro-poetic world of today. Twitter, with its limitation of 140 characters, has surprisingly provided a platform for all manner of short form poetry celebrating many of the mundane, and eternal themes such as love, life, death, and the natural world. Perhaps, even Basho would accept that in the 21st century we should be allowed to express ourselves more freely and decide the contents of the haiku rule book - if we have one. Simplicity & beauty should be the main aim.
