Maha Shivarathri
Mahāśhivarāthri is celebrated for the worship of Lord Śhiva and falls on the 14 th day in the Kriṣhṇa Pakṣha of the month of Phālguna (around February or March).
According to Hindu mythology, when the Gods (Dhevas) and Demons (Asuras) churned the sea for Amrutha, a deadly poison came out of the sea which was so toxic that it could wipe out the entire creation from this Universe. On the advice of Lord Viṣhṇu, the Gods approached Lord Śhiva and pleaded with him to save the universe. Pleased with their prayers, Lord Śhiva drank the entire poison and held it in his throat. Though his throat became blue he was not harmed. However, the doctors advised Lord Śhiva to be awake the whole night as a part of the medication. So the Gods played music and performed dances to amuse Lord Śhiva the full night. To commemorate this, devotees fast, pray and offer coconut, Bilva leaves and sacred food to Lord Śhiva and keep awake the whole night to mark the occasion.
