There’s an evanescent quality to this life. It keeps on changing. And we know that—but we don't really know it. I think if we really knew it, we wouldn’t spend a moment angry. The more I go on, the more I think that the development of poise is the heart of practice: whatever is happening, that’s okay; this thought came up, that’s okay; this feeling came up, that’s okay; my back hurts a bit, that's okay. Then we do whatever we can to calm down our mind, because it’s not about armwrestling your mind to the ground, but reminding it of what’s true.
