Golden Sand in the Eye
You are all familiar with Buddha's story, sitting under the Bodhi Tree, getting enlightenment. Somebody once asked a great master about Buddha's enlightenment, and this master said: "Golden sand in the eye."
Zen students want enlightenment, but the problem is that as soon as you want something, this something is binding; it becomes your prison. Whether this prison is golden and beautiful, or bad and terrible, still prison is prison. So, if you are attached to something, want something, then already you don't get freedom.
