When I was young (it feels funny to write that, but I’m 48 now, and some things have changed), I was drawn towards the furthest edge, the place where the sea meets the sky, the distant horizon. Sometimes it felt like the knife’s edge. I lived in extremes, out on a limb, fully extended, in all senses, including physical practice. Part of this for me was an attempt to feel my own edges, and I believe this is connected to my hypermobility, since the receptors relating to stretch and physical position don’t give the same feedback in a hypermobile body that they do in bodies with normal-range tissue density. It’s hard to feel where I end and where I begin. It’s only as I’ve grown older that I’ve learnt to lean into the middle ground, and still now I would say that I don’t feel easy there.
I have battle scars from my time on the far edge. But do I regret going there? I cannot in honesty say that I do. I am reminded of words I heard in a play a few weeks ago: ‘Perhaps young men need to fight.’ And perhaps when we are young we need to push our bodies, we need to take risks. Boxers, skateboarders, ballet dancers, gymnasts, freerunners … Inhabiting the physical extreme may just be what young people do.
I preface these reflections on edge in this way because I don’t want to pathologise myself or anyone else who has pushed it as far as it will go; I want to witness all the possible orientations to edge rather than decree that any one is correct. But do I teach this kind of edge to students? Do I advocate it? No, I guide them gently away from the cliff edge and into the middle ground.
If we set out to boil hatha yoga down to the bones, the principle of edge would probably be one of the things left at the bottom of the saucepan. It’s crucial to practising with awareness. When we begin yoga, particularly in the dynamic forms, many of us don’t have much of this kind of awareness. Working on the edge may be synonymous for us with going to our limit. It’s in the nature of astanga vinyasa, because of the escalating physical challenges it presents, to attract people who like to dance on the brink of the precipice. It may be only when injury or exhaustion forces us to re-evaluate our practice that we begin to question the wisdom of habitually hanging on by our finger-nails. As we start to explore our physical, psychological and emotional experience more subtly, we may discover that the brink is not the only edge, that in fact there is a spectrum of edges, each one representing a different degree of intensity.
Eric Schiffmann describes the multiplicity of edges like this:
Each pose has a ‘minimum edge’ and a ‘maximum edge’, as well as a series of intermediary edges between these … [The maximum edge] is the point where the stretch begins to hurt. It is the furthest point of tightness beyond which you should not go. If you were to force yourself beyond this point, you would definitely be in pain and might hurt yourself or pull a muscle. The minimum edge is where you sense the very first sensation of stretch, the very first hint of resistance coming from your muscles.
He suggests that we can approach each succeeding edge as a gateway. Once we have fully experienced the sensations at a particular gate, we may pass through and onto the next. The intention is not to race through the final gate, but to be as present as we can to the threshhold where, moment by moment, we find ourselves. In other words, edge is not one place or a single arrival; it’s never discovered, mapped, done and dusted. Edge is an ongoing process, an endless dance of shifting experience. Nor is the edge really separate from us. There’s no thin black line out there against which we in here pit ourselves. Edge is intrinsic, a unique product of the interplay between our individual body and psyche with a particular asana in a particular moment in time.
For me, now, the edge is a place where, moment by moment, I experience some kind of physical, and/or psychological, and/or emotional expansion. In other words, something is happening. Something might be a memory or a feeling surfacing into consciousness; it might be a knot of matted fascia releasing; it might be a new technical ability coming within my grasp. Now I often see edge not as the furthest out but as the place between. If I force my body, if I approach my practice with more or less subtle aggression, I create physical, mental and emotional contraction. Everything tightens, closes in. This happens quite literally: force is experienced by the body as trauma; contraction is the body’s physical response to trauma. If, on the other hand, I am complacent, sluggish, too comfortable, I create a different kind of contraction, one that results from a kind of entropy. Again, this happens quite literally. Fascia contracts if not stretched regularly; muscles waste if not used. The edge between these two places is the not-too-much-not-too-little location where expansion is possible – in body, mind and bodymind.
Cultivating an awareness of how we relate to edge is important in the immediate sense because it enables us to practise without injuring ourselves physically (and without giving up and going to eat chips). Beyond that, though, our relationship with edge on the mat has everything to tell us about how we meet with edge in our life. If we reflexively back away from challenge in yoga practice, choosing postures that we find easy and non-threatening, remaining in the shallows emotionally and physically, this is a reflection of how we will pitch our edge in life. Likewise if we practise yoga constantly on the verge of pain, at the outer limit of our endurance, our flexibility, our capacity for emotional presence, this will be the edge we choose in the rest of our life. Many of us go on habitually redrawing the same patterns in the sand and wondering why they never look any different. By giving attention to these patterns in the laboratory of our practice, we become gradually more able to recognise them in life, and as we learn to recognise them, we can slowly begin to choose new trajectories.
Astanga vinyasa involves a process of dynamic surrender. ‘Dynamic’ means hanging on in there, offering the best of our energy and our sense of direction. It means staying awake. ‘Surrender’ means letting go into the reality of exactly what is in each moment – which may be that we don’t have much energy, we’ve lost our way and we’re falling asleep. Learning to walk this edge skillfully requires a lot of practice – which is why we practise every day. The more we practise, the more we find there’s space around the edge to play. We develop finesse and audacity. We may choose to take a risk, not out of inner compulsion but because danger is a facet of human experience and so we include it in our exploration.
My favourite image of edge is Philippe Petit wire-walking between the Twin Towers. I guess he was out on a limb there. He certainly had finesse and audacity, and once, after all the planning that almost never came off, he actually made it onto the wire, there was a sense of expansive, ecstatic ease. For me, this moment represents the point at which the edge dissolves and we find ourselves abiding in the still point at the centre, suspended in pure presence.
