There are so many questions one could ask about practice: What does it mean to “practice” mindfulness? Is it necessary to practice in a formal way, such as sitting meditation or yoga? If one is going to have a formal practice, then how long and how often? Or is it enough to let the practice opportunities come spontaneously, such as remembering to pause (STOP) at a tense moment, or fully experiencing your surroundings in the middle of a busy day? These are not questions anyone else can answer for us – each of us must find our own way to renew or maintain mindfulness in our lives, one that resonates with who we are. This is a continual journey, one that is a practice in itself.

There are countless ways to practice mindfulness. If you go to Miribai Bush's Tree of Contemplative Practices, you'll see that only one of the many practices described is a sitting meditation - others include yoga, journaling, Tai chi, walking/hiking. (In the Introduction video, I mistakenly say that "art" is not one of them, but art is there, too, listed as "Contemplative arts".) If you click the above link, it will take you to a graphic of this tree, and clicking on any of the branches takes you to a description of a particular practice.

    For those seeking balance in their lives, a certain flexibility of approach is not only helpful, it is essential. It is important to know that meditation has little to do with dock time. Five minutes of formal practice can be as profound or more so than forty-five minutes. The sincerity of your effort matters far more than elapsed time, since we are really talking about stepping out of minutes and hours and into moments, which are truly dimensionless and therefore infinite.
    So, if you have some motivation to practice even a little, that is what is important. Mindfulness needs to be kindled and nurtured, protected from the winds of a busy life or a restless and tormented mind, just as a small flame needs to be sheltered from strong gusts of air. If you can only manage five minutes, or even one minute of mindfulness at first, that is truly wonderful. It means you have already remembered the value of stopping, of shifting even momentarily from doing to being…
    Forming the intention to practice and then seizing a moment - any moment - and encountering it fully in your inward and outward posture, lies at the core of mindfulness. Long and short periods of practice are both good, but "long" may never flourish if your frustration and the obstacles in your path loom too large. Far better to adventure into longer periods of practice gradually on your own than never to taste mindfulness or stillness because the perceived obstacles were too great. A journey of a thousand miles really does begin with a single step. When we commit to taking that step - in this case, to taking our seat for even the briefest of times - we can touch the timeless in any moment. From that all benefit flows, and from that alone.

    Always remember that in training a puppy we want to end up with the puppy as our friend. In the same way, we must practice seeing our mind and body as "friend." Even its wanderings can be included in our meditation with a friendly interest and curiosity. Right away we can notice how it moves. The mind produces waves. Our breath is a wave, the sensations of our body are a wave. We don't have to fight the waves. We can simply acknowledge, "Surf's up." "Here's the wave of memories from three years old." "Here's the planning wave." Then it's time to reconnect with the wave of the breath. It takes a gentleness and a kind-hearted understanding to deepen the art of concentration. We can't be present for a long period without actually softening, dropping into our bodies, coming to rest. Any other kind of concentration, achieved by force and tension, will only be short-lived. Our task is to train the puppy to become our lifelong friend.
    The attitude or spirit with which we do our meditation helps us perhaps more than any other aspect. What is called for is a sense of perseverance and dedication combined with a basic friendliness. We need a willingness to directly relate again and again to what is actually here, with a lightness of heart and sense of humor. We do not want the training of our puppy to become too serious a matter.
