Mandavya

Curse
Mandavya (Sanskrit: माण्डव्य) was a sage, who according to Hinduism, was wrongly punished by the king by being impaled. This occurred as the chief of a band of robbers had hidden their stolen goods in a corner of his hermitage when he was in deep contemplation, and he was wrongly assumed to have stolen the goods. Lord Yama gave him this punishment for having tortured birds and bees in his childhood. In response, Mandavya cursed the Dharma, as his punishment exceeded the sins committed as an ignorant child. Therefore he cursed him to be born in the mortal world. He was born as Vidura, the wise, to the servant maid of Ambalika, wife of King Vichitravirya, who offered her to Sage Vyasa in place of Ambalika

Wife

Maudgalya, well versed in all the four Vedas, and to whom Nalayani was married. By a quirk of fate, he took upon himself to test the chastity and devotion of his wife Nalayani and with the yogic powers that he had acquired brought on himself old age, a nauseating foul odour emanating from his body and the debilitating disease, leprosy. Undaunted, Nalayani served him with all wifely devotion, attended to each and every small detail that would keep him happy, in spite of the fact that he was never satisfied with her services and finding fault with her even for small omissions. 

Nalayini ate only after he had partaken his food, and only the leftovers on the same plate as he had eaten. One day, she noticed one of his fingers in the left over food. Without feeling any revulsion, she removed the offending digit from the food and ate food as if it was nectar. Rishi Maudgalya wanted to enjoy the company of another woman, a vesi, who would sell her favours only for gold. Nalayani parted with her gold chain. He commanded his wife to carry him in a basket on her head, to the house of the prostitute. The ever obedient Nalayini with great care bundled his infirm old bones, in a big basket and carried him on her head, through the streets, to the house of the prostitute, to the accompaniment of the derisive laughter of the on lookers. 

While hurrying and unable to perceive the predicament of Rishi Mandaviyar, Nalayani's head load of Rishi Maudgalya brushed against the two feet of the dangling Rishi. Out of excruciating pain and able to see the perpetrator of the crime was none other than Nalayani and her husband, he cursed her: "By the time the Sun rises tomorrow you will lose your husband and you will become a widow. This is certain, because you have hurt me at my vitals." Nalayani, the Pathivratha Shironmani, the chaste and virtuous lady, pleaded with him to take back his curse, because what had happened was a mere accident and unintentional. But it was of no use. Rishi Mandaviyar was firm and adamant. 

Absolutely aroused, and in mortal fear of losing her husband, Nalayani drew herself erect with her headload, and called on the Indradi Devas, and the other Gods as witness: "If at all, I have lived the life of a chaste woman, dedicating myself to serving my Lord and Master and if my husband must die at sunrise tomorrow, then I decree, that the Sun will not rise forever". After intervension of demi-gods and others, Rishi withdrawn his curse and the sun began to shine as usual. 

Nalayini, by the power of chastity, stopped the rising of the sun to save her husbands's life as well as got relief from the curse.
