What lesson is shown in the story Bowaon and totoon?

Bowaon and Totoon show the value of cooperation. Both brothers have unique strengths—Bowaon could provide for their food, while Totoon is good at building strong shelters for himself and his younger brother. They are stronger together—when they decide to live separately, each of them fails to succeed at the most basic tasks; the two of them manage to catch prey and build a new house when they decide to combine their efforts again.
