Importance of Pradosh Vrat
Devotees pay respect to Mahadev (Lord Shiva) and celebrate his victory over the demons. They offer prayers and express gratitude during Pradosh Kaal on the Trayodashi Tithi. According to Indian mythology, Lord Shiva and his vahana (mount) Nandi rescued devas from asuras. The gods had visited Kailash (Lord Shiva's heavenly abode) during Pradosh Kaal. Lord Shiva and Nandi fought a battle and defeated the asuras.
