Shankha
The conch shell, the special emblem of Vishnu, and a trumpet still blown in Hindu worship.
Meaning
The conch, the discus and the mace are the weapons peculiar to Vishnu, in T. A. Gopinatha Rao’s account, and the conch is almost always in one of the hands of his images. According to Hinduism Today it stands for the cosmic vibration of the sacred sound Om. In temple worship its call marks the important moments: the opening of the sanctum doors, the beginning of arati, the lamp offering, and the end of an abhishekam, when a sacred image is bathed. Many households keep a conch in their shrine. A conch used to pour water in abhishekam is left whole; one blown as a horn has a hole cut at one end.
Origin and history
The Monier-Williams dictionary records the shankha from the Atharvaveda, and notes that in the battles of epic poetry each hero carries a conch as his trumpet, often with a name of its own. In the first chapter of the Bhagavad Gita Krishna blows Panchajanya and Arjuna blows Devadatta. Vishnu’s conch was said to come from the body of an asura, Rao records, and Vishnu blew it in war to strike terror into his enemies; in images, though, it is treated as a bugle more than as a weapon.
Left-turning and right-turning
Most conches spiral to the left when seen from the wide end: these are vamavarta shankhas. The rare right-turning ones, the dakshinavarti shankhas, are considered the most auspicious, according to Hinduism Today.
How it is carved
Rao describes two forms in sculpture: a plain conch held by its open end, and an ornamented one with a metal cap topped by a lion’s head and a cloth tied round it.
In other traditions
The conch is also one of the eight auspicious symbols of the Buddhism of East Asia and the Himalayas (see Right-turning conch).
