The Kalika Purana narrates the following tale about Rati's birth. After the creation of the 10Prajapatis, Brahma – the creator-god – creates Kama (Kamadeva), the god of love, from his mind. Kama is ordered to spread love in the world by shooting his flower-arrows andPrajapati Daksha is requested to present a wife to Kama. Kama first uses his arrows against Brahma and the Prajapatis, who are all incestuously attracted to Brahma's daughter Sandhya ("Twilight-dawn/dusk"). Shiva, who was passing by, watches them and laughs. Embarrassed, Brahma and the Prajapatis tremble and perspire. From the sweat of Daksha rises a beautiful woman named Rati, who Daksha presents to Kama as his wife. At the same time, the agitated Brahma curses Kama to be burnt to ashes by Shiva in the future.
However on Kama's pleading, Brahma assures him that he would be reborn. The Brahma Vaivarta Purana narrates that Sandhya committed suicide, after Brahma lusts for her. GodVishnu resurrects her and names her Rati, and marries her to Kama. The Shiva Puranamentions that after her suicide Sandhya is reborn from the sweat of Daksha as Rati In some texts, the god Shiva is described as the father of Rati.
The demon Tarakasura had created havoc in the universe, and only the son of god Shiva could slay him, but Shiva had turned to ascetic ways after the death of his first wife, Sati. Kama was thus instructed by the gods to make Shiva fall in love again. Kama went to Mount Kailash with Rati and Madhu or Vasanta ("Spring"), and shot his love-arrows at Shiva (in another version of the legend, Kama entered Shiva's mind) and invoked desire. Wounded by Kama's arrows, Shiva becomes attracted to Parvati, the reincarnation of Sati, but agitated, burns Kama by a glance of his third eye.

The Bhagavata Purana narrates further that the grief-stricken Rati goes mad by Kama's death and in the Matsya Purana and the Padma Purana versions, she smears herself with her husband's ashes. Further in Bhagavata Purana, Rati undergoes severe penance and pleads with Parvati to intercede with Shiva to restore her husband. Parvati reassures her that Kama would be reborn as Pradyumna, the son of Krishna, the Avatar of the god Vishnu on earth, and Rati should wait for him in the demon (asura) Sambara's house. In other versions of the narrative like the Matsya Purana, the Padma Purana, the Shiva Purana, the Linga Purana and the Kathasaritsagara, it is Shiva who blesses Rati with the boon of Kama's resurrection. In other variants, she curses the gods who sent Kama for this doomed mission and the gods, as a group or Brahma, seeks relief for the grieving Rati from Shiva or the Supreme Goddess, Parvati being one of her many manifestations. In some legends, like the one in the Brahmanda Purana, the Goddess revives Kama immediately, hearing the pleading of the wailing Rati and the gods. The renowned Sanskrit poet Kalidasa dedicates canto IV discussing the plight of Rati in his Kumarasambhava, which focuses on the story of the wedding of Shiva and Parvati and the birth of their son Skanda, who kills Tarakasura. Canto IV narrates that Rati witnesses the death of her husband and laments his death, and then tries to immolate herself on a funeral pyre. A heavenly voice stops her on time, stating that after the marriage of Shiva, he will revive her husband.
