In my opinion, the problem with NLP and metaphor is that NLP attracts and is
marketed to people who are far more at home with lists, facts and
conscious-style logic than those who have a natural leaning towards the far more
fluid, information rich and interactive form of data flow that is metaphor.
Metaphor can't be learned by studying examples of metaphor, or by learning
lists of metaphorical objects and occurrences by heart; metaphor can't be
"drilled" (eeouwh! that hurts, so bad ...) and most of all, metaphor can NEVER
be understood by dissecting language into its component pieces.
So the main method by which NLP analyses strategies and language is
essentially entirely unsuitable for teaching or even understanding the organic
processes of metaphor. What is to be done?
