"People aware of their own birth and death in this way are said not to be lacking. Not lacking in what? Not lacking in birth. They're acquainted with the births they've experienced through many lives and states of being in the past—so many that they're weary of it all, to the point where they don't want to take birth again. As for people who don't know, who don't have this awareness, they feel that they're lacking. They want to take birth again and so they keep on creating birth over and over again. As for those who do have awareness, they've had enough. They're smart enough. They won't give rise to any more births or states of being. Whatever is good, they keep within themselves, like putting a ripe mango seed in a showcase to look at, or peeling off its hard outer shell and then putting it in a storeroom. No one will be able to plant it again, and we can take it out for a look whenever we want."
