I've seen this story in several places. I don't know who to attribute for it.
I think it reveals an important way of thinking.
| There is a story about an old Rabbi who once asked his disciples how
they could tell when the night had ended and the day began. The disciples
thoughtfully considered the Rabbi’s question.
“Could it be,” asked one student, “when you see an animal
in the distance and can tell whether it’s a sheep or a dog?”
“No,” replied the Rabbi.
“Could it be,” another asked, “when you look at a tree
in the distance and can tell whether it is a fig tree or a peach tree?”
“No,” said the Rabbi again.
“Well then, when is it?” his pupils demanded to know.
“It is when you can look at the face of any man or any woman and
see that he is your brother or she is your sister. Because if you cannot
do this, then no matter what time it is, it is still night.”
All men are my brothers and all women are my sisters. I sometimes forget that,
and have to continually remind myself of it, so remembering this story helps.
