Thank you Lew for this evocative haiku. As with Marion, I had never heard of virga before and looking it up I was immediately transported by your poem. It shows how the selection of the perfect descriptive word can be so much more powerful than sentiment in making a poem affect us.
This poem also makes me reflect on another feature of our favourite poetry form – how Tinywords offers us all the opportunity to travel the world, to different times and seasons, through verse. Of course Basho when he popularized the modern form did so in the literary form he apparently invented – poetic travel journals, in which the verse was written to capture his aesthetic experience of the places he visited – often as part of a literary pilgrimage (inspired by his own poetic hero, Saigo, 5 centuries earlier).
This poem is likewise able to evoke for me a place where I have never been, and am unlikely ever to visit, but I can draw from these spare descriptive lines a sense of oppressive heat and the cruel poignancy of the place. (Though I would really have loved to have further enriched the experience with a few lines of haibun to enter into and share your own encounter prompting the work.)
