I came across a page on internet that has a story of Lord Shiva's sister Devi Asavari. The article said that since Devi Parvati felt lonely on Mount Kailash being the only lady there, so she asked Lord Shiva to create a female companion or a sister-in-law for her. Lord Shiva obliged to that on the condition that Devi Parvati has to keep her female companion happy, to which Devi Parvati agreed. Thus, Lord Shiva created a lady similar to him in knowledge and powers who was later came to be known as Devi Asavari. Initially Devi Parvati was happy with her but later she disliked her for her heavy eating habits and rude nature.
The story is given on link : https://googleweblight.com/i?u=https://www.newsgram.com/know-why-goddess-parvati-asked-lord-shivas-sister-devi-asavari-to-leave-kailasha/&grqid=SaFe96JS&hl=en-IN
Can anyone please tell me whether is is an authentic story and taken from any puranas or other religious text or its just a folklore. Also, if there is any other story(s) or mention of her anywhere else, then please let me know the same.
