When one enters the water carrying a rhinoceros horn, the water will be kept away by 5 feet. When a leaf of sandalwood opens, the bad odor of eraṇḍa will disappear as far as 40 yojana (distance covered by a traveling man in 40 days). The evil karma of ordinary people is like the water and the eraṇḍa and the daimoku of the Lotus Sūtra is like the rhinoceros horn and leaf of sandalwood.
