Suppose a child gets a present of one of these glass balls and they’ve never seen one before. They shake it and then set it down to watch the snowstorm subside. They don’t have to learn how to watch it subside. It doesn’t come with instructions. They don’t have to practice how to watch it subside. They don’t have to be told how to watch it subside. By themselves they know how to make the snow fall again, and how to keep it still for the storm to settle.
“Since before the time when nothing existed, this essence has been ever still and unmoved, determining the basis of all conscious beings. It permeates all times and is beyond all thought. It is beyond holy and ordinary and transcends all knowledge and views. It has never fluctuated or wavered: it is there, pure and naked and full of life. All beings have it complete within them.” - Zen master Yuanwu
