Shiva is the third important God according to Hindu belief. People who desire to have a successful married life as that of Shiva and Parvati, offer prayers to Shiva and Shivaling. The Shivaling symbolizes the phallus, which is considered as a symbol of Shiva.
Mercury or parad or para in Hindi, is also known as Shivdhatu,or Shiva’s metal. In reality, it refers to Shiva’s semen. Shivaling are made from a different stones. But it is believed to possess divine qualities as it is made from mercury.
The blessings of Shivaling is considered to be equivalent to those from hundreds of Ashwamedh yagyas or giving millions of cows in charity. Even giving gold as charity cannot also equal the blessings earned from a Shivling. Offering prayers to the Shivling at home, keeps all bad things away and success becomes the permanent member of your home. Even vaastu shortcomings can be ignored by praying the Shivling. Prayers on every Monday to the mercury Shivaling can also help you be protected from the tantrik spells.
In Shiv Mahapuran, Shiv has said:
Whatever blessings are showered upon you on making offerings to millions of different Shivalings these can be multiplied manifold when you personally offer prayers to the mercury Shivaling. By a mere touch of the mercury Shivaling one can achieve salvation.
