The Master once exposed his disciples by means of the following advice:
He gave each of them a sheet of paper and asked them to write down the length of the hall they were in.
Almost everyone gave flat figures like fifty feet. Two or three added the word approximately.
Said the Master, “No on has given the right answer.”
“What is the right answer?” they asked.
“The right answer is I DO NOT KNOW,” said the Master.
