Across from my home, there is a field with two horses in it.  It seems that each horse looks like any other far away.  But if you get a closer look, you will see the bigger horse is blind.

But if you stand nearby and listen, you will hear the sound of a bell.  It is coming from the neck of the smaller horse in the field.  It lets the blind friend know where the other horse is, so he can follow him.

As you stand and watch these two friends, you’ll see that the horse with the bell is always checking on the blind horse and that the blind horse will listen for the bell and then slowly walk to where the other horse is, so that he will not be left（落下）.

When the horse with the bell returns to the barn(畜棚) each evening, he will stop from time to time to look back, making sure that the blind friend isn’t too far behind to hear the bell.

Sometimes we are the blind horse, and at other times we are the horse, helping others to find their way.
