Rudrabhishek pooja is a Vedic Hindu ritual dedicated to Lord Shiva, performed by ceremonially bathing the Shiva Lingam with holy substances like milk, honey, and water, while chanting mantras like the Shri Rudram. The puja aims to invoke the blessings of Lord Shiva (in his fierce “Rudra” form) for prosperity, health, and the removal of negativity and obstacles. It is considered a powerful ceremony to wash away sins and gain spiritual peace.
