"why mustn’t it fail?"
Why mustn’t -- He fails.

                                     Trenched in the sand, from whence It hails?
From the mirages treacherous, Thenceforth It prevails, yet,
Implore He must, Its ignorance prevails.
It fights Its fights; Its inquiries It derails:
It is a because, not a why not a may(be).

                               He; shallow his origin as the queries He concocts
why must He question, why mustn’t... He fails.
