3.37 Kama esah etc.  A total absence of difference among these two (desire and wrath)  is indicated by the word esah  'this'  twice uttered.  These desire and wrath are ever interrelated and remain in an inseparable mutual co-existence.   Hence [the Lord]  well describes them only  as identical.

This is man of intelligence  should view to be an enemy.
