Note: This post is not advocating a new distraction yoga mashup of the type that I’ve been known to rant about, but is merely a discussion of the synergy to be found in practicing both yoga and poetry.
In Patanjali’s conception, the problem for which yoga presents a solution is the mind’s tendency to run amok. One would like to be able to hold the awareness on a given object, effortlessly and for extended periods of time, but the mind is insistent in its desire to roam. This roaming can be to many different ends, but often it’s ultimately about eliminating uncertainty. The mind wants a plan against the unexpected. It seeks solutions to problems — existing, anticipated, or imagined. It wants to replay entertaining stories, which is really a way to learn and store general solutions for later surprise problems that might otherwise catch one off-guard. The more anxious or emotionally charged the mind, the more turbulent it will be.
Poetry is the use of metaphor, imagery, and sound to strike an emotional chord. I don’t mean “emotional” exclusively in the sense of displaying strong, behavior-driving emotions. I mean all sorts of internal, subjective feelings, including nostalgia and the residue of memories and dreams.
Sometimes, the feelings a poem seeks to generate are primal emotions. For example, consider Emily Dickinson’s poem “A Narrow Fellow in the Grass”  (about a snake, if you didn’t make that connection) that concludes:
But never met this FellowAttended or aloneWithout a tighter BreathingAnd Zero at the Bone.
Or, from Poe’s “The Raven:”
Deep into that darkness peering, long I stood there wondering, fearing,Doubting, dreaming dreams no mortal ever dared to dream before;
O to go back to the place where I was born!To hear the birds sing once more!To ramble about the house and barn, and over the
fields, once more,And through the orchard and along the old lanes
So, emotion is the connection. Poetry helps one form, shape, and refine emotional content, and yoga helps one to experience that emotion without applying value judgments or allowing the motive force of emotion to drive one into endless cycles of destructive feedback. That is, one feels the need to think about an emotionally charged situation, and the more one thinks about it, the more intense the emotion becomes, and the more intense the emotion, the more one thinks about it. I’ll just call this process “wallowing” — wallowing in emotion.
The word “emotion” carries with it a lot of baggage. Emotion is often juxtaposed with rationality / reason, which isn’t accurate. (Reason works great for making decisions when there is adequate information, emotion forces one to move one’s ass when there isn’t sufficient information. So they are not so much opposites as complimentary systems supporting decision and behavior.)
In the common conception, emotion also tends to be more linked to the expression of emotion rather than the experience of emotion — which are necessarily related. (Some people very readily express intense emotion despite an easy life and others are non-expressive despite constant uncertainty or even challenges to survival.) When one imagines someone unburdened of emotion — e.g. fearless — one might picture a hero — bold and courageous — but what one sees among people who suffer afflictions (e.g. brain damage) that prevents them from feeling emotion is often paralysis by analysis. Without emotion to make decisions under uncertainty, such individuals simply get bogged down. Individuals who don’t feel fear, in particular, are also prone to carelessness.
The key to making one’s yoga and poetry practices simpatico is avoiding that very popular form of poetry — the wallowing poem. If one’s poems constantly spiral into ever greater depths of angst (as many a famous — and, sadly, suicidal — poet’s work has been known to) you might want reevaluate. And, perhaps, start with haiku and that forms Zen distaste for hyperbole or analysis.
