Thank You again, and again you are welcome. Writing usually begins as an 'inner feeling' (can be sentient or audient) first before it even gives rise to a thoughtform and only then is followed by action of putting pen to paper. If one concentrates only on finished form, that preconceived form is very limiting as all must fit neatly into that box which is not always the case. It is nice to have no box, no walls no boundaries right? Alliterations do not need to be structured either as they flow with ease once one is connected to all and remains open to all.
The haiku as a device though brief is just that hopefully a brief connection an 'Aha' and a gentle tug or even yank into any given moment or perhaps the subject sharing the moment with the poet. Again indication to not try to hold on to any moment just 'let if flow' and receive them as they come.
7 seems to be Magic for most minds and perhaps additional series of 3's may be added yet there is more outside of psychology or rather inside that is not so limiting So alliteration and mnemonic devicing can help also recognition of patterns and observation which comes from 'letting go' and 'letting it flow' 20 lines? so the music helps. So hum is good!
