Today across India people are celebrating religious festival Mahashivaratri with zeal and zest and it is associated with Lord Shiva (God of destruction), and lot of stories behind the celebration of this festival found.Some of them are -
Once Lord Shiva and his wife Sati or Shakti were returning from sage Agastya’s ashram after listening to Ram Katha. On their way through a forest, Shiva saw Lord Rama searching for his wife Sita who had been kidnapped by Ravana, the King of Lanka. Lord Shiva bowed his head in reverence to Lord Rama. Sati was surprised by Lord Shiva’s behavior and inquired why he was paying obeisance to a mere mortal. Shiva informed Sati that Rama was an incarnation of Lord Vishnu. Sati, however, was not satisfied with the reply, Lord asked her to go and verify the truth for herself.Using her power to change forms, Sati took the form of Sita appeared before Rama. Lord Rama immediately recognized the true identity of the Goddess and asked, "Devi, why are you alone, where's Shiva?" At this, Sati realized the truth about Lord Ram. But, Sita was like a mother to Lord Shiva and since Sati took the form of Sita her status had changed. From that time, Shiva detached himself from her as a wife. Sati was sad with the change of attitude of Lord Shiva but she stayed on at Mount Kailash, the abode of Lord Shiva.Later, Sati’s father Daksha organised a yagna, but did not invite Sati or Shiva as he had an altercation with Shiva in the court of Brahma. But, Sati who wanted to attend the Yagna, went even though Lord Shiva did not appreciate the idea. To her great anguish, Daksha ignored her presence and did not even offer Prasad for Shiva. Sati felt humiliated and was struck with profound grief. She jumped into the yagna fire and immolated herself.Lord Shiva became extremely furious when he heard the news of Sati’s immolation. Carrying the body of Sati, Shiva began to perform Rudra Tandava or the dance of destruction and wiped out the kingdom of Daksha. Everybody was terrified as Shiva’s Tandava had the power to destroy the entire universe. In order to calm Lord Shiva, Vishnu severed Sati's body into 12 pieces and threw them on earth. It is said that wherever the pieces of Shakti’s body fell, there emerged a Shakti Peetha, including the Kamaroopa Kamakhya in Assam and the Vindhyavasini in UP.Lord Siva was now alone undertook rigorous penance and retired to the Himalayas. Sati took a re-birth as Parvati in the family of God Himalaya. She performed penance to break Shiva’s meditation and win his attention. It is said that Parvati, who found it hard to break Shiva’s meditation seeked help of Kamadeva - the God of Love and Passion. Kaamadeva asked Parvati to dance in front of Shiva. When Parvati danced, Kaamadeva shot his arrow of passion at Shiva breaking his penance. Shiva became extremely infuriated and opening his third eye that reduced Kaamadeva to ashes. It was only after Kamadeva’s wife Rati’s pleading that Lord Shiva agreed to revive Kaamadeva. Later, Parvati undertook severe penance to win over Shiva. Through her devotion and persuasion by sages devas, Parvati, also known as Uma, was finally able to lure Shiva into marriage and away from asceticism. Their marriage was solemnized a day before Amavasya in the month of Phalgun. This day of union of God Shiva and Parvati is celebrated as Mahashivaratri every year.
One legend concerns Lord Shiva and his divine consort, Maa Parvati. After creation was complete, Parvati once asked Lord Shiva which day did he like the most. The Lord replied that the 13th night of the new moon, during the month of Magha, is his most favourite day. Parvati told this to her friends, from whom the word spread over all creation. Hence, Mahashivaratri is observed on the 13th day of Magha.
According to anther legend, at the time of churning of samudra, a pot of poison emerged from the ocean. This terrified the Gods and demons as the poison was capable of destroying the entire world, and they ran to Shiva for help. To protect the world from its evil effects, Shiva drank the deadly poison but held it in his throat instead of swallowing it. This made his throat turn blue, and he was given the name Neelakantha, the blue-throated one. Shivaratri is the celebration of this event by which Shiva saved the world.
As per another legend in the Shiva Purana, once the other two of the triads of Hindu Gods, Brahma and Vishnu, were fighting over who was the superior of the two. Horrified at the intensity of the battle, the other gods asked Shiva to intervene. To make them realize the futility of their fight, Shiva assumed the form of a huge column of fire in between Brahma and Vishnu. Awestruck by its magnitude, they decided to find one end each to establish supremacy over the other. Brahma assumed the form of a swan and went upwards and Vishnu as Varaha went into the earth. But light has no limit and though they searched for thousands of miles, neither could find the end. On his journey upwards, Brahma came across a Ketaki flower wafting down slowly. When asked where she had come from, the Ketaki replied that she had been placed at the top of the fiery column as an offering. Unable to find the uppermost limit, Brahma decided to end his search and take the flower as a witness. At this, the angry Shiva revealed his true form. He punished Brahma for telling a lie, and cursed him that no one would ever pray to him. The Ketaki flower too was banned from being used as an offering for any worship, as she had testified falsely. Since it was on the 14th day in the dark half of the month of Phalguna that Shiva first manifested himself in the form of a Linga, the day is especially auspicious and is celebrated as Mahashivaratri. Worshipping Shiva on this day is believed to bestow one with happiness and prosperity.
Once King Sagar the ruler of Ayodhya and an ancestor of Lord Rama successfully performed the Ashwamedha Yagya for 99 times. Each time, he sent the horse around the earth it returned to the kingdom unchallenged. However, Indra - the King of God’s became jealous of King Sagar’s success. So when King Sagar performed the sacrifice of the 100th time, Indra kidnapped and hid the Yagya horse in the hermitage of Kapila Muni.In search of the horse, sixty thousand princes from Ayodhya reached Kapila Muni’s hermitage. They mistook the sage to be the abductor and attacked him. An enraged Kapila Muni burnt the 60,000 princes to ashes. On hearing about the plight of his father and uncles, King Bhagiratha - one of the grandchildren of King Sagar requested Kapila Muni to grant a solution to the problem. Kapila Muni advised that the waters of the river Ganga would miraculously bring back the dead princes to life.King Bhagiratha left his kingdom and began to mediate for the salvation of the souls of his ancestors. It is said that Bhagiratha observed a penance to Brahma for a thousand years, requesting Ganga to come down to earth from heaven and wash over his ancestor's ashes to release them from a curse and allow them to go to heaven. Pleased with the devotion, Brahma granted Bhagirath’s wish but told him to pray to Lord Shiva, as he alone could sustain the weight of her descent. Accordingly, Lord Shiva held out his thick matted hair to catch the river as she descended. The meandering through Shiva’s lock softened Ganga’s journey to the earth and the holy waters of river Ganga thus washed away the ashes of Bhagirath’s ancestors. A modified version of the legend says, what reached the earth were just sprinkles from Lord Shiva’s hair. The Ganga, thus, became an attribute of Shiva. This manifestation of Shiva is known as Gangadhara.
The legend is re-enacted by devotees of Lord Shiva as they give a bath to the Linga during worship. And for this reason, many devotees prefer to take a dip in the holy water of river Ganga on a Shivaratri day.
