Sometimes creating a poem is nothing more than a rite of exorcism, a catharsis by which you cast out a demon skulking about your interior landscape, exiling it to the surface of a sheet of plain white paper ... From A Rite of Exorcism Variations in the Perception of Color is a collection of work by poet Howard Brown. The author reflects on the world, interesting people with whom he has interacted, the unique character of animals, the effect of nature on the mind, the ongoing pandemic, and the purpose of poetry. While exploring his personal experiences, he meanders deftly between the real world and that of the imagination, exploring how things might have turned out in slightly altered circumstances. His poems reveal that poetry is often akin to a dream - a means of expression that challenges the capacity of words.
