Maha Shivaratri

Maha Shivaratri is a Hindu festival of Nepal and India celebrated annually in reverence of the God Shiva. While most Hindu festivals are celebrated during the day, Shivaratri is celebrated during the night by keeping a "jaagaran" - a night-long vigil as its believed that Lord Shiva saved the universe from darkness and ignorance. This day is believed to be the day that Shiva was married to the Goddess Parvati. The Maha Shivaratri festival, also popularly known as 'Shivaratri' (spelt as Sivaratri, Shivaratri, Sivarathri, and Shivarathri) or 'Great Night of Shiva', marks the convergence of Shiva and Shakti. Maha Shivaratri is celebrated on the Krishna Paksha Chaturdashi of Nepali Calendar|Bikram Sambat Calendar on the month of Falgun as per Amavasya-ant month calculation. As per Poornima-ant month calculation, the day is Krishna Paksha Trayodashi or Chaturdashi of Bikram Sambat calendar month Falgun which falls in February or March as per the English Gregorian calendar. Of the twelve Shivaratris in the year, the Maha Shivarathri is the most holy.
The festival is principally celebrated by offerings of Bael leaves to Shiva, all-day fasting and an all-night-vigil (jagaran). All through the day, devotees chant "Om Namah Shivaya", the sacred mantra of Shiva. Penances are performed in order to gain boons in the practice of Yoga and meditation, in order to reach life's highest good steadily and swiftly. On this day, the planetary positions in the Northern hemisphere act as potent catalysts to help a person raise his or her spiritual energy more easily. The benefits of powerful ancient Sanskrit mantras such as Maha Mrityunjaya Mantra increase greatly on this night.
