A very stout devotee came to Periyaval with a complaint. He said that he suffered from blood pressure, diabetes and excessive cholesterol and other such chronic problems.
No matter how much of medication he took and went on a strict diet, he just could not lose weight. The gentleman was a Nattukottai Chettiar.
"It is good that you go to Tiruvannamalai. Stay there for a mandala. Circumambulate the hill.
When you cannot walk, take an auto or go by car, but somehow complete the circumambulation.
Walk one kilometer, then taken an auto... what do you say?"
The Chettiar did as he was told. A week later his weight began to go down. At the end of the maandala, he had lost so much weight that he was almost normal.
When the mandala was completed, he came to Periyava and prosptrated.
"Why! You are able to prostrate without difficulty!" Periyaval told the devotee.
The gentleman glowed in happiness.
