The sound that’s heard from the conch seashell is said to be symbolic of the sacred ‘Om’ sound which is believed to be the very first sound of creation. This is why the conch is blown before any ritual or ceremony since it represents good luck and marks the start of any positive or auspicious work. Even today it’s believed that when the conch shell is blown, the environment around it will be purified from all evil and good fortune will enter.
