“Monks, suppose that this great earth were entirely covered with water, and a man were to toss into that water a plank of wood with a large hole in it. The wind would blow that wooden plank every which way–west and east, south and north. Now suppose that there were, in that world-covering ocean, a blind sea turtle, which came to the surface only once every hundred years. Now, monks, how likely is it, do you think, that the old blind turtle, surfacing after one hundred years, would come up with his head through the hole in that plank?”
“Not very likely, Master. If that turtle were to come up with his head through the hole in that plank, it would be the rarest of chances.”
“That’s just how rare a chance it is that one is born into the human state. And it’s likewise by the rarest of chances that a Wayfarer, worthy and rightly self-awakened, arises in the world. And it’s the rarest of chances that the Dhamma and Discipline proclaimed by the Wayfarer shines in the world. And now, you have attained this human state. And now, a Wayfarer, worthy and rightly self-awakened, has arisen in the world. And now, the Dhamma and Discipline proclaimed by the Wayfarer shines in the world.
