A conch is a sea-dwelling mollusc. It is popularly referred to as "Shankha" in the Hindu faith was considered among the most auspicious and sacred objects that emerged during the Ksheera Sagara Samudra Manthan from the sea.

A Shankha (conch shell) is blown to start religious ceremonies. A Shankha in one hand and a disk or a chakra on the other is shown in the images of God Vishnu, the god of protection. The Shankha is an essential part of Hindu symbolic and religious beliefs. To date, all Hindus use the conch as a part of their religious ceremonies. It is said that whenever the Shankha is blown it purifies the environment of all negativity.

The importance of the conch shell can also be supported by science, leaving aside the mythological element. You can hear the sound of the softly humming ocean when you try to hold a Shankha near your ear. Basically, this is the normal vibration or cosmic force of the planet, magnified when it reaches the Shankha.

The vibrations of these shells can overcome the negativity and also clearly detect environmental damage, including healing the ozone layer causing global warming.

The Shankh is an embodiment of Lord Ganesha as it naturally looks like the shape of Ganesha's face. It is considered to ward off obstacles, evil spirits, and negativity. Ganesha is worshipped as the lord of beginnings, of obstacles (Vighnesha), a patron of arts and sciences, and the god of intelligence and wisdom. Ganesha Shankh is always worshipped, at the beginning of any religious rituals, blessings, and auspiciousness. According to astrology, a Ganesha Shankh removes all obstacles which come in the path of devotees.
