Coral and Marine Products Protectives.
Next in value to these metals come coral and other marine products, which in the case of the Hindus probably derive their virtue from being strange to an inland-dwelling people, and as connected with the great ocean, the final home of the sainted dead. Coral is particularly valued in the form of a necklace by those who cannot afford the costlier metals, and its ashes are constantly used in various rustic remedies and stimulants. In Gujarât a coral ring is used to keep off the evil influence of the sun,[34] and in Bengal mourners touch it as a form of purification. According to the old belief in England, coral guarded off lightning, whirlwind, tempests and storms from ships and houses, and was hung round the necks of children to assist teething and keep off the falling sickness.[35] So with shells, particularly the Sankha or conch shell, which is used for oblations and is regarded as sacred to Vishnu. It is blown at his temples when the deity receives his daily meal, in order to wake him and scare off vagrant spirits, who would otherwise consume or defile the offering. This shell, in popular belief, is the bone of the demon Panchajana, who, according to the Vishnu Purâna,[36] “lived in the form of a conch shell under the ocean. Krishna plunged into the water, killed him, took the shell, which constituted his bones, and afterwards used it for a horn. When sounded it fills the demon hosts with dismay, animates the gods, and annihilates unrighteousness.”
All these shells appear to derive part of their virtue from the fact that they are perforated. The cowry shell, which is worn round the neck by children as an antidote to the Evil Eye and diabolical influence, is supposed to have such sympathy with the wearer that it cracks when the evil glance falls upon it, as in England coral was thought to change colour and grow pale when its owner was sick. The cowry shell is, with the same object, tied round the neck or pasterns of a valued horse, or on a cow or buffalo. The shell armlet worn by Bengal women has the same protective influence.[37]
