3.4-5 Na karmanam etc Na hi etc.  Knowledge, deserted by action, does not exist;  and the action, combined with dexterity does not exist,  [if it is] deserted by knowledge. Therefore knowledge and action constitute one and the same thing.  Hence it has been delclared :
 
    'Knowledge is not deserted by action and action is
         not deserted by knowledge.  [Hence]  a teacher who
         is well accomplished in knowledge and action, is
         the cutter of the fetters of the fettered'. 
 
Therefore the action that is included within the knowledge cannot be avoided.  For, the body, the organ of speech and the mind are, by nature, in a perpetual motion; and hence an individual, being simply under the control of other than himself, necessarily performs one action or the other.  For, the body, the speech-organ and the mind are of the nature of throbing.
