to HIKU or HAIKU that is the question

HAIKU  is a centuries old Japanese traditional phonetical & cultural poetic form whereas HIKU is a relatively recently established English language version thereof 'birthed' from last half of the 20th century. Hiku is an imagist tristich like its elder cousin,without a title,and with a similar economy of words ,inherently enigmatic & with a caesura or an ellipsis and surprise ending. A similar sense of pause the aesthetic insight flowing from perception gained from 'one breath length ' composition that flowed from the  Japanesese 17 onji sound inherent in the haiku. Without  any syllabic( 5-7-5 ) line restrictions, the hiku is the 'free verse' version of the haiku,similar but different ,a present tense poetic in another language - hiku is the written or recited equivalent to arts 'gestural spontaneous happening' .
