My father-in-law first turned me onto the concept of flow with a book by psychologist Mihaly Csikszentmihaly, called Finding Flow, and his research into what he called “optimum experience” many years ago. Flow is likened to a moving meditation. It's the product of about 150 years of research into a neuropsychological phenomenon where it has been observed every action and every thought leads effortlessly or flows fluidly and near perfectly into the next. Although there are some differences between meditation and flow, both are tools for cultivation. One that has studied internal martial arts or yoga could easily make an argument that the definition of flow and meditation are quite blurred. If you ever “lost” an afternoon due to a great conversation or just got so sucked into a project that everything else is forgotten, you have probably had this experience. In flow, our concentration gets so hyper-focused that everything, nonessential, just falls away. Action and awareness start to merge. Our sense of self and consciousness seems to vanish completely. Time dilates- which means it can slow down so you get that freeze-frame effect like you're in a car crash or it can speed up where 5 hours can pass by in what seems like 5 minutes. This is otherwise known as the “deep now”. As our brains lose executive function time conflates. The prefrontal cortex is saving energy and can't be bothered doing calculations right now. We begin to step into this timeless moment. This brings up interesting ideas on stress. Stress now is not present moment stress. Stress instead is what has already happened in the past or what could happen in the future. Since our brains are now processing this information in this deep now...performance goes up and those stresses go down. Studies on anxiety and PTSD have shown that five weeks of surfing (an activity that has tons of flow triggers) along with talk therapy can all but completely eradicate PTSD in soldiers. More recently the same study was done, but this time the trigger was meditation and practitioners got the same results in four weeks. That's amazing when you compare it to drug therapy, which does not have the same positive results.
