Question of a master to his disciples:
___ "How do you know the night is over and it's daylight? "
A disciple answered:
___ "When you see a person from a distance, you can discern whether it is a man or a woman. "
But the master refused the answer with a nod.
Another aspirant says:
___ "When you see a tree and see if it is a mango tree or an apple tree. "
But this answer proved just as incorrect.
The master smiles and says:
___ "When you see in every man a brother and in every woman a sister, it is the end of the night and the beginning of the day.
Until then, even if the sun illuminates the earth in the middle of the day, it is night and you are in darkness. "
