4.16-17 Kim  karma etc.  Karmanah  etc.  The classification of  [good]  action  and  non-action  is difficult to comprehend.  That is to say  there is bad  action  even among the action  that  has been  ordained [in the scriptures], just as the animal-slaughter  in the [pious]  Agnistoma  sacrifice.  Again, even in the  midst of action,  that goes against  [the scripture],  there is  auspicious  action;  for example there is an end for the trouble of the people in the act of  killing	 a murderous animal.  Even in the case of non-performance of action,  there do exist  [both]  the auspicious and inauspicious acts;  for there will be necessarily  [some]  acts performed  by the sense of speech  and by the mind  as they are  difficult to avoid  without  wisdom.  Therefore on account  of its mysterious nature, even hte experts have not properly understood the action as :  'Prosperity  would be for as by this  [particular]  auspicious  action;  and emancipation would be for us by that  [particular]  non-undertaking  of [certain]  actions'.  Therefore,  it is the fire of wisdom  taught  in the seel,  that alone is capable  of positively  burning  down the  fuel of all the auspicious  and inauspicious  actions;  and hence  that is to be  sought after as a refuge.
