Maha Shivratri is a Hindu festival celebrated every year in reverence of Lord Shiva. Shivaratri literally means the great night of Shiva or the night of Shiva. It is celebrated every year on the 13th night/14th day of the Maagha or Phalguna month of the Hindu calendar. The festival is principally celebrated by offerings of Bael or Bilva/Vilvam leaves to Lord Shiva, all-day fasting and an all-night-long vigil. Maha Shivaratri is celebrated with great devotion and religious fervor by Hindus, in honor of Lord Shiva. Many interesting legends have been related to the festival of Maha Shivaratri, explaining the reason behind its celebrations as well as its significance.
According to one of the most popular legends, Shivaratri is the wedding day of Lord Shiva and Parvati. It is also believed that Lord Shiva performed the dance of the primal creation, preservation and destruction on this auspicious night of Shivaratri. According to another popular legend, described in Linga Purana, it was on Shivaratri that Lord Shiva manifested himself in the form of a Linga for the first time. Since then, the day is considered to be extremely auspicious by the devotees of Shiva and they celebrate it as Maha Shivaratri - the grand night of Shiva.
Shiva devotees observe strict fast on Maha Shivaratri, with many people having only fruits and milk and some not even consuming a drop of water. As Shiva is regarded as the ideal husband, unmarried women pray for a husband like Him, on Shivaratri. On the other hand, married women pray for the well being of their husbands, on this auspicious day.
On Maha Shivratri, devotees wake up early in the morning and take a bath, if possible in river Ganga. After wearing fresh clothes, they visit the nearest Shiva temple, to give ritual bath to the Shiva Lingum (with milk, honey, water etc). The worship continues the whole day and whole night. Jaagran (nightlong vigil) might also be observed in Lord Shiva temples, where a large number of devotees sing hymns and devotional songs, in praise of Lord Shiva. In the morning, devotees break their fast by taking the prasad offered to Lord Shiva, after the aarti, the night before.
