Hello AG,
thank you for having dealt so intensively with the poem, its message and the amazement of the commenting users.
I think the author does not want to make the reader accept an opinion, a belief. She points out exactly what you make clear: Reality is there, there is not much we can do about it. But it is up to us how we view reality. We decide for ourselves whether we want to inflict (mental) pain on ourselves by looking at it or not. The linguistic translation of this essence by the poet is a work of art!
To you and your loved ones a good start into the New Year, an eventful and healthy 2020!
Virtual embrace,
Chriddi
