Feel it.
If you hear a crack in the skull, describe it as best you can.
Don't tell all. Hide what you want to say. Let the reader find out what you want to say.
A poem is a different genre. It is not a news article or essay or other journalistic writings.
The reader of a poem experiences a feeling beyond words. Needless to say, the reader is not experiencing what the poet experienced; it may be the result of what he reads in the poem.
"If you cannot write clearly, that's because either your head is muddled or you are too afraid to reveal your true feelings and thoughts. To me, clarity is a great virtue of the intellect."--a character in "A Map of Betrayal," a first-person novel by Ha Jin

"If tomatoes wanted to be melons,
they would look completely ridiculous.
I am always amazed
that so many people are concerned
with wanting to be what they are not;
what's the point of making yourself ridiculous?"--Mitsuo Aida, Japanese poet, and calligrapher
