This is not my story. It was told to me in about 1990 by a friend – an admirer who went to pay homage to BKS Iyengar and stayed at his ashram.
He wanted to meet the master and was granted an audience.
After the meeting the acolyte who accompanied him out of the building asked how he had found the experience. “The guru is angry”, said my friend.
“So would you be,” said the acolyte “if you stood on your head four hours a day!”
Rest in Peace Guru
