There are several traditions of how KaliKali
There are several traditions of how Kali came into existence... came into existence. One version relates when the warrior Durga, who had ten arms each carrying a weapon and who rode a lion or tiger in battle, fought with Mahishasura He was a demon who had the power to transform into a buffalo at will. He was blessed by Brahma that no man could kill him. He wanted to take over the heaven and conquer the universe. Durga failed him in his attempt by fighting and killing him. According to some legends, he is believed to be a great devotee of Durga, who played her enemy on her request as she wanted to teach the value of heaven to various Gods(or Mahisa), the buffalo demon. Durga became so enraged that her anger burst from her forehead in the form of Kali. Once born, the black goddess went wild and ate all the demons she came across, stringing their heads on a chain which she wore around her neck. It seemed impossible to calm Kali’s bloody attacks, which now extended to any wrongdoers, and both people and gods were at a loss what to do.
Fortunately, the mighty ShivaShiva
Shiva is one of the Supreme Gods of Hindu Trinity that ... stopped Kali’s destructive rampage by lying down in her path, and when the goddess realised just who she was standing on, she finally calmed down. From this story is explained Kali’s association with battlegrounds and areas where cremation is carried out.
here is the another story of the terrible demon Raktabija (Blood-seed). This demon was, like most demons, causing a great deal of trouble with people and gods alike but even worse was his ability to produce more demons every time a drop of his blood spilt to the ground. Therefore, each time Raktabija was attacked, the only result was more demons to deal with. The gods decided to work together and combine all of their shakti or divine energy and produce one super being that could destroy Raktabija; the result was Kali She is the embodiment of empowerment and a fierce aspect of the Goddess. She is black in her complexion and thus she is named Kali. She is the Goddess of time, power, change and destruction and is majorly worshipped in South India, Bengal and Assam(in another version only Durga produces Kali).
Given all the divine weapons of the gods, Kali swiftly sought out Raktabija and his demons and proceeded to swallow them all whole so as not to spill anymore blood in the process. Raktabija himself was killed when Kali lopped off his head with a sword and then drank all of his blood, making sure none fell to the ground and thereby ensuring no more demons could menace the world.
In another version of the goddess’ birth, Kali appeared when ParvatiParvati
After the death of Shiva's first love Sati, Shiva... shed her dark skin which then became Kali, hence one of her names is Kaushika (the Sheath), whilst Parvati is left as GauriGauri
Gauri is another form of Parvati who is known for her fair skin and radiance. She is a gentle goddess who is kindhearted and nurturing... (the Fair One). This story emphasises Kali’s blackness which is symbolic of eternal darkness and which has the potential to both destroy and create.
In a third version, men and gods were being terrorised by Daruka who could only be killed by a woman, and Parvati was asked by the gods to deal with the troublesome demon. She responded by jumping down Shiva’s throat. This was because many years previously Shiva had swallowed Halahala, It was one of the assests of SamudraManthan, a poison that could end the universe but was consumed by Lord Shiva to save the universe from destruction the poison which had risen from the churning of the ocean during the creation and which had threatened to pollute the world.
By combining with the poison still held in Shiva’s throat, Parvati was transformed into Kali. Leaping from Shiva’s throat in her new guise, Kali swiftly despatched Daruka and all was well with the world once more.
