How is mindfulness practice translated into everyday life?

First of all, what is meant by the term "mindfulness"? Most people understand it in a limited and limiting way of just being aware of the present moment experience. But even though that in itself is a huge task and an enormous challenge for the average person, it is just part of the requirements to live up to the standard put up by the Enlightened One. In my understanding, mindfulness implies a continuous willingness to be and stay with anything that arises in order to see it clearly, to understand its dynamics and to than evaluate the best, the most wholesome way to deal with it. And that's where it gets tricky. Being with any kind of experience without judging or criticizing it, can easily be misread as "nothing really matters, be equanimous with any sort of sensation, feeling or interaction with other people". Then enlightenment can be seen as unwavering happiness, bliss and not caring. But as a matter of fact, even the Buddha experienced physical pains and sorrows, so what is really meant by mindfulness? It's the understanding that all phenomena, whether pleasant, painful or neutral, they all have 3 universal characteristics. Impermanence, stressfulness and not-self. Take your time and contemplate whether this is truly the case or not. Is there anything never changing, endlessly satisfying and fit to be called you or yours? There is a succession in these 3 characteristics, which makes it more sensible or obvious. Because everything is changing, no matter how pleasant or painful, it's unreliable and leading to suffering either when it subsides or, if unpleasant, right at the spot of its arising. So this is quite crucial! With unpleasant or painful experiences we easily see the stressfulness or suffering in them. But to understand that also pleasant and enticing sense pleasures are inherently stressful and leading to suffering, because of their impermanent nature. So wanting pleasures to stay indefinitely is equally deluded as wishing unpleasant or painful experiences to stop and go away. Through extensive mindfulness practice in meditation and contemplation one can slowly and steadily strengthen the mind and heart to step back from any sense experience and see their impermanent, stressful and selfless nature. Joseph Goldsteins Teacher called it very pointedly "empty phenomena rolling on". Because everything is unstable and stressful, nothing is fit to be called "I, me or mine". So one recommendation I offer is to train yourself in taking a step back whenever you become aware of an experience and instead of thinking "I am happy" or "I'm angry" or "I'm sad" or even "I want this or that" to refrase it internally to: "There is happiness, anger or sadness present". "There is wanting or aversion". This process allows you to become centered and stable enough to look at what is actually happening and to investigate the 3 universal characteristics of impermanence, stressfulness and not-selfness. The more often you can do that and see for yourself, the more everything opens up to make life a lot broader, richer and less stressful. Try it out. Come and see.
