Bilva Patra Arpan means offering Bilva Patra. The Bilva Tree is considered sacred, and the Bilva Tree leaf is the most favorite of Lord Shiva. The Bilva Patra represents the trinity of Brahma, Vishnu, and Shiva. Bilva Patra has three gunas – Sattva, Rajas, and Tamas – which create all aspects of creation. Bilva Patra has also been given importance in Ayurveda due to its medicinal properties. The three leaves of the Bilva tree are called Bilva Dal, which is considered a representation of Trishul, the weapon of Lord Shiva. By performing Bilva Patra Puja, devotees receive the blessings of Lord Shiva.
