Yes, I take poetry seriously.
As seriously as I take a mountain. A lake. A river. A face.
Poetry is indistinguishable from life. Sure, poetry is made of words. But so is life. Try to imagine getting through life without any words. Not even the words in your head. Not even your name.
I submit to you that words, like the four cardinal directions (or numbers themselves), are archetypal. This means they exist outside of the speaker, but they also create the speaker.
In some sense, we're all poets. The archetypal nature of our consciousness makes any other possibility impossible. The poet in me may be very different than the poet in you -- at least on the surface -- but the impulse to sing, to explore, explain, and even confess is equally alive in all of us, without exception.
That's why we should take poetry seriously.
The word geas stands atop an interesting etymology. To do magic, one commonly casts a spell; to make poetry, one must spell. The grammar of magic is found in grimoires, whereas the grimoire of consciousness is found in the grammar of poetry.
No matter who the poet, or what the theme, the spell of poetry is intrinsically joyous. It's born of the pure levity that abides in the Universal or Kether mind. If you prefer, it's the language of the unconscious, which holds in its unknowable abyss, the purest joys of the cosmos.
In any case, we can take poetry seriously without fear of injury or sickness because it's the stream of life. It's life that threatens to turn us ill, particularly when we forget, willfully or not, that whoever we happen to be standing next to, texting, or even ignoring is also a poet just like we are.
