"What is one'e life journey like?"
    "Tis a swan alighting on snow mud,
       per chance leaving a few prints.
  Where does the swan fly?
   The mud knows not east or west."

    This poem was written by Su Dong Po, famous Chinese poet of Sung Dynasty.  He lived 1037-1101.   Though there's no mention of violence in the poem, it is assumed that  one is upright, and wouldn't do a thing as harming another.  And what Su, Dong Po meant was that, one is free 2 do whatever they please.  No one keeps track or limits them.
    The above interpretation is directly from my mother, Dr. Alice B.G. Wei,  (Univ. of Chicago, 1974, Asian History).
