Jon Kabat-Zinn said this quote

Mindfulness practice means that we commit fully in each moment to being present. There is no performance. There is just this moment. We are not trying to improve or to get anywhere else. We are not even running after special insights or visions. Nor are we forcing ourselves to be non-judgmental, calm, or relaxed. And we are certainly not promoting self-consciousness or indulging in self-preoccupation. Rather, we are simply inviting ourselves to interface with this moment in full awareness, with the intentino to embody as best we can an orientation of calmness, mindfulness, and equanimity right here and now.Of course, with continued practice and the right kind of firm yet gentle effort, calmness and mindfulness and equanimity develop and deepen on their own, out of your commitment to dwell in stillness and to observe without reacting and judging. Realizatinos and insights, profound experiences of stillness and joy, do come. But it would be incorrect to say that we are practicing to make these experiences happen or that having more of them is better than having fewer of them.
