If we hope to go anywhere or develop ourselves in any way, we can only step from where we are standing. If we don't really know where we are standing... We may only go in circles.
Jon Kabat-ZinnMindfulness meditation is the embrace of any and all mind states in awareness, without preferring one to another.
Jon Kabat-ZinnTo let go means to give up coercing, resisting, or struggling, in exchange for something more powerful and wholesome which comes out of allowing things to be as they are without getting caught up in your attraction to or rejection of them, in the intrinsic stickiness of wanting, of liking and disliking.
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.
