Fall reminder

As the days grow shorter, the night comes sooner and daylight arrives later, I am reminded of this Chasidic story: 

A wise old rabbi asked his students how to determine that day has come. Among a number of religions, this is important for determining when certain things need or must be done. In the Quran, for example, rules for fasting during the day say that day comes when you can distinguish a light thread from a dark one.

Some students suggested that it is day when you can see your hand at the end of your arm. Others contended that it was day when you can distinguish a man from a tree in the distance. 

The rabbi shook his head.

"Day has come, when you look into the face of any man or woman and recognize your brother or sister. Until then the night is still here."
