One need not dive into Vedas and other treatises to undertand the significance of Lord Shiva, the lord of the lords. A simple and small story all parents love to tell their kids reveals all. Once Lord Shiva and Parvati had a fruit and wished to give who between Ganesh and Kartikeya goes round the universe first. Off went Kartikeya, the army-chief of the gods, on his mighty peacock with a supersonic speed while Ganesh with his tiny carrier, a mouse, was left to plan his journey. Wily Vignesh, the one who surmounts all the obstacles, went round his parents three times to win the sweet fruit!
That is what Lord Shiva is... the whole of the creation, the universe divined by none other than Lord Ganesh, the god of learning and wisdom.
None has seen Lord Shiva with a crown, ever poorly dressed, the god of the poor common man. He had no palaces. Ever below the poverty line (BPL), he was indeed above all the riches. When we see by two eyes, He had the third eye for vision. With no beginning and no end, Adyantahin, He stood for purity and is eternal. He is the musician, He is the dancer. He is the destroyer too. He is param Yogi.
This day is celebrated across India, specially in Kashmir, with great gusto and fanfare. People fast on this day and keep awake the whole night. At midnight a giant lamp is taken to the top of the Lingaraj Temple at Bhubaneswar, Orissa. The devotees in large number go ecstatic. Great celebrations take place at Varanasi, Somanath in Gujarat, Ujjain, Haridwar, Srikalahasti (Andhra Pradesh), Madurai, Rameshwaram, Nasik and at every Shiva temple.
'Boloji' on this auspicious day worships at the lotus-feet of this Formless and prays for His blessings to all of us.
