The shell is one of the eight auspicious symbols of Tibetan Buddhism and represents the glory of the teachings of Buddha, who like the sound of the conch shell that spreads in all directions. Conch or Conque, also known as a "seashell horn" or "shell trumpet", is a wind instrument that is made from a conch, the shell of several different kinds of sea snails. A tone hole can be added to change the fundamental frequency but globally this is extremely rare, thus most conches are natural horns.
In Tibet, Conch Shell Trumpet is also known as Sankha. It is blown by people in Tibet. The sound of the Conch Shell proclaims the glory of the holy name. This instrument is blown into the temples of Hindus and Buddhists in prayer or meditation. It is advised to face the Conch Shell’s mouth outside of the house or shop entrance to attract fortune in.
