In Indian mythology, the Shankha is regarded sacred and very auspicious. To initiate religious ceremonies, a shankha (conch shell) is blown. It is a major Hindu article of prayer. God Vishnu, the God of Preservation, is shown with a shankha in one hand and a disc or a chakra in the other.

Each hindu shankha has a specific name. Vishnu's shankha is called "Panchajanya" . It is believed that when it is blown, it announces the victory of good over evil. In the epic war, Mahabharata, the conch shell held a significant place. Arjuna's shankha was called "Devdutta" , Bhima's "Paundra", Yudhisthira's "Anantavijaya", Nakula's "Sughosa" and Sahadeva's was known as "Manipushpaka".

The sacred conch shell is an integral part of Hindu symbolic and religious tradition. Even today, all Hindus use the conch as a part of their religious practices. Whenever the conch shell is blown, it is said to purify the environment from all evil effects.

Scientific significance

Leaving aside the mythology part, the conch shell's significance can also be corroborated by science. If you try holding a shankha near your ear, the sound of the gently humming ocean can be heard. This is actually the natural vibration or cosmic energy of the Earth which gets magnified on entering the conch shell.

The vibrations from these conch shells can overpower evil forces from the Earth and at the same time also clear environmental pollution including healing the hole in the ozone layer which causes global warming. According to science, the blowing of a conch shell enhances the positive psychological vibrations such as courage, determination, hope, optimism, willpower, etc. in the blower as well as those around him.

The shankhas that open towards the right hand are called Dakshinavarti Shankhas. These shahkhas are rare and are available in white color with brown lines on them that run towards the right or South.

Traditionally, a Dakshinavarti shankha is similar in its piousness from the earthly incarnation of Vishnu or Lakshmi themselves and the blessings of Lakshmi literally flow out of the remaining shell on their own. Dakshinavarti shankhas not only bring wealth but also purify the atmosphere. All the negatives energies are swept out of the place.

Vamavarti Shankha

The shankhas that open towards left hand are Vaamavarti Shankhas. These are the most commonly available shankhas and used for all religious purposes. In fact, most of the conches are Vaamvarti, that is, their bulge opens towards left side (facing North).

The special geometry of a natural shankha creates a positive energy field and so they are used as Yantras. Some astrologers also recommend the types of shankha and the location where these are to be placed to control negative planetary effects. Different methods of worshipping the shankhas are also described in the Indian scriptures for benefits varying from wealth, success and peace of mind to health, healing and hypnotism.
