The Swami used to wear sandals of very high quality called Sakalaath Paadarakshaa made at Tanjore. He had said, if jatilingam ( a compound of mercury and sulphur) is kept within sandals which a Suddha dehi ( a man of perfect and pure body wears on, it will stand against fire or endure in the heat of fire (i.e., without melting). A devotee priest namely Sabhapathy had special sandals prepared for the Swami in which four tolas of the said mercurous compound had been kept. At his request, the Swami wore the sandals for 15 days and then later on the mercurous compound was removed from them and it was observed to withstand the heat of fire without change.
