On certain occasion, while dusk was approaching, a Master asked his disciples if they knew how to tell when the night ended and the day started.
The first of them said:
—When you see an animal at the distance and you can distinguish if it is a cow or a horse.
—No —said the master.
—When you see a tree at the distance and you can distinguish if it is a pine or an eucalyptus.
—Not either —said the master.
—It’s OK —said the disciples—, tell us, when is it?
—When you look at a man at his face and recognize in him your brother; when you look at the face of a woman and recognize in her your sister. If you’re not able to do this, then, be whatever hour it be, still it’s night for you.
