[Meister] Eckhart has much to say about the saying, "Blessed are the poor in spirit," which is the most illuminating statement in the Bible. What does "poor" mean here, asks Eckhart. He replies: "The poor man, the one who is poor, is the one who wants nothing, knows nothing, and has nothing."
[Upon awakening] a Zen monk said, "Last year my poverty was something like the point of a drill, a very small point. My poverty was such that I had nothing but the small point of a drill. This year my poverty is such that there is no drill, and there is no ground in which its point could be inserted. So I am entirely poor."
This corresponds to what Eckhart means...The mind must be entirely empty of the things we generally put in it. When this takes place there is real God, that is, real poverty---not to want anything, not to know anything, not to have anything.
