This is a very special night for worshippers of Lord Shiva. It’s the commemoration of Shiva’s Tandava or sacred dance. In his title of Nataraja (lord of the dance), Shiva cleanses away bad karma, brings blessings, and balances the Universe. 
It is commemorated on the sixth night of the Phalguna, the lunar-solar month between February and March in India. Usually either on the Full Moon or the New Moon. In this case this New Moon that we will be entering soon (tonight is the celebration). Besides this being the anniversary of when he first did the Tandava, it’s also his wedding anniversary to Lady Parvathi. Because of this, this night is just as important and sacred for Lady Parvathi as it is for anyone else.
Offerings of fruits and flowers as well as Bel leaves are given. Veneration of the Shiva Lingham as well is good for today as well as fasting all night. And the Mantras are the (1) “Om Namah Shiva” and the “Maha Mrityunjaya” (especially good for the bringing of blessings).
“Om Namah Shivaya” (ॐ नमः शिवाय) meaning “Adoration to Shiva” or “I bow to Shiva”. That’s the easiest one. The other one is slightly more complex.
Translations in English from the original language,
Maha Mrityunjaya Mantra
ॐ त्र्यम्बकं यजामहे सुगन्धिं पुष्टिवर्धनम्
उर्वारुकमिव बन्धनान् मृत्योर्मुक्षीय मामृतात्॥
Om Tryambakam Yajamahe Sugandhim Pushti-Vardhanam
Urvarukamiva Bandhanan Mrityormukshiya Mamritat॥
Meaning:
“We concentrate on our third eye which lies behind the two eyes and this gives us the power to feel you and by this we feel happy, satisfied and peace in life. We know immortality is not possible but some extension can be given to our death by your powers Lord Shiva,” (2)
I like to listen to them as religious music when I do my ceremony for them in my home. In my home I give honor to their idols both inside my house and on the outside property. I give not just the usual offerings mentioned above but the first and last portions of the food I eat. Libations of sweet drink and candles and incense. These are the links to some really good musical renditions of these mantras.
I fast as much as I can but eventually I have to eat. I abstain from sexual activity as part of my cast which I do till next morning. I listen to each for an hour long as I do my rituals.
So on this most sacred and holy night, give offerings to both Shiva and Parvatbi and beg their gracious indulgence! May the Lord and Lady watch over you this night and for the rest of the year!
