I was on a short vacation last week and saw a preserved fragment of the Diamond Sutra from the Dunhuang collection.
Of course the Diamond sutra gets referenced occasionally in the zen tradition, so here is my reference-ception where I reference the Book of Serenity, where Wansong references National Teacher An referencing the Diamond Sutra
National Teacher An brought up the Diamond-Cutter Scripture, saying, " 'You should enliven the mind without dwelling on anything.'--not dwelling on anything means not dwelling on form, not dwelling on sound, not dwelling on delusion, not dwelling on enlightenment, not dwelling on essence, not dwelling on function. Enlivening the mind means manifesting one mind in all places: if you enliven the mind dwelling on good, goodness appears; if you enliven the mind dwelling on evil, evil appears--the basic mind is concealed. If it doesn'e dwell on anything, anywhere, the whole world is one mind."
-Commentary on Case 74 in the Book of Serenity
My reaction is basically "what is there for the mind to dwell on in the first place?"
