It happened when President Kim Il Sung received a foreign party delegation on a visit to the DPRK.
When the head of the delegation asked him how to strengthen the party, the President asked him back if he knew the way the bees live.
And he said that just as the bees live in a group and in an orderly manner centring around a queen, there should be a centre and discipline in the collective, adding that in order to strengthen the party, the whole party should first and foremost be firmly united with the leader as the centre.
After listening to what he spoke in plain language, the head of the delegation said in admiration:
“The President clearly told me the fundamental principle of party building in a single teaching. Your teaching has a deep meaning and is easy to understand. Only a great man penetrating the universe can do so.”
