Together in harmony

I was walking from the  temple area back to the class and my attention was caught by a beautiful scene.  Two huge bulls were lying on the grass resting and a black bird landed on the back of one of them.  It walked back and forth until the bull waived the tail with a little annoyance (not much though).  The bird then jumped on the one other bull, walked on its back and then started sliding on its legs as if it decided to choose a snowboarding career.  It would slide down then ran quickly to the top of  the leg and slide again.  Then the bird went to another leg, then it ate something in the grass but without leaving the bull's leg and then finally this black bird flew away.  Two bulls continued lying in the grass enjoying the sun.
