Often in Western culture to be strong is to be tough, rigid and immovable. In Chinese culture, there is a concept called Wu Wei. It means ‘The art of non-action,’ it is embracing flow instead of effort to achieve a result. Essentially, it means being flexible, like water and being present in the moment, in a state of flow.
In Wu Wei if you strive for something you miss the point. A goal can be achieved through effortless action, through being so engaged with the task at hand that time passes and the work is done. It is to do and not to try.
When you are doing something you enjoy time passes by almost unnoticed and you go where the activity takes you. You do the thing you are doing without concentrated effort. Applying this to the rest of tour life is Wu Wei.
