Mindfulness is a way to rebalance ourselves. Instead of being lost in thought, or caught up in emotional upheaval, we can tip the scale in the direction of greater equanimity, clarity, wisdom, and self-compassion by actually learning how to inhabit that other dimension of our being.
Jon Kabat-ZinnAnother way to look at meditation is to view thinking itself as a waterfall, a cascading of thought. In cultivating mindfulness, we are going beyond or behind our thinking, much the way you might find a vantage point in a cave or depression in the rock behind a waterfall. We still see and hear the water, but we are out of the torrent.
Jon Kabat-ZinnWhen people say "Let it go," what they really mean is "Get over it," and that's not a helpful thing to say. It's not a matter of letting go - you would if you could. Instead of "Let it go," we should probably say "Let it be"; this recognizes that the mind won't let go and the problem may not go away, and it allows you to form a healthier relationship with what's bothering you.
Jon Kabat-ZinnI thought it was a stroke of genius that Hans Selye used the word stress, because it's true that if you don't know how to be in wise relationship to life, certain health consequences are bound to happen. If you stand up 12 hours a day on an assembly line, or constantly tell yourself life is not worth living, the body will respond in certain somewhat predictable ways.
