"The sand (Hindi: mitti) in the arena is especially holy to them. In Benares it [sand] comes from the Ganges and is mixed with Ganges water, mustard oil, and turmeric in order to keep it soft and supple. On special occasions, milk and clarified butter (ghi) are also added. The ground must be turned, loosened, and renewed periodically. Only the master (Hindi:ustad) is allowed to enter the new sand after he has honoured it with flowers and incense. The young men not only rub themselves with sand, they also wallow in it. Sand is the balm for their heroism."
