It is not just nature that defies us. Human life is as overwhelming... If we spend time in it [the vast spaces of nature], they may help us to accept more graciously the great, unfathomable events that molest our lives and will inevitably return us to dust.
I have seen a thousand graves opened, and always perceived that whatever was gone, the teeth and hair remained of those who had died with them. Is not this odd? They go the very first things in youth and yet last the longest in the dust.
Those who know don't talk. Those who talk don't know. Close your mouth, block off your senses, blunt your sharpness, untie your knots, soften your glare, settle your dust. This is the primal identity. Be like the Tao. It can't be approached or withdrawn from, benefited or harmed, honored or brought into disgrace. It gives itself up continually. That is why it endures.
I do value my work awfully; but in reality only consider this: all this world of ours is nothing but a speck of mildew, which has grown up on a tiny planet. And for us to suppose we can have something great - ideas, work - it's all dust and ashes.
