Usha, the daughter of
Daitya king
Banasura, fell in love with
Aniruddha, the son of
Pradyumna and grandson of Lord
Krishna. After their marriage they were reborn as Behula and Lakshindar in their next life and again married each other. Behula was the daughter-in law of
Chand Sadagar of Champaknagar. According to history, two beautiful
Apsaras of the heavens, Usha and Aniruddha were cursed by the gods as per the plan of Devi
Manasa and sent to earth as Behula and Lakshinder - Behula as the only daughter of Saybene (or Sayven of Ujaninagar) and Lakshinder as the seventh son of Chand Sadagar. Chand Sadagar was a great devotee of Lord
Shiva and for certain reasons, hated Devi Manasa. In order to obtain the position of a goddess in heaven, Manasa had to get "anjali" by the right hand of Chand Sadagar - the Bhaktasreshto. However, Chand vowed to never give anjali to Manasa by his right hand (which he used for giving anjali to Shiva only). To get an anjali from him, Manasa took away the lives of his six sons who died from poisonous snake bites (Devi Manasa had absolute power over all snakes). These deaths further infuriated Chand Sadagar, who vowed to save his last son Lakhinder in any way possible. Chand got to know about Behula, whose horoscope spoke that she could never be widowed. He then got Lakshinder married with Behula, and also had an iron palace built without any holes in it, to ensure that no snake could enter it. The divine architect
Vishwakarma had built this palace for the wedding night of Behula and Lakshinder. When requested by Manasa, he left a hole in the palace. On the wedding night, Manasa sent her most poisonous snake Kalnagini to the couple's room and cast a spell on Behula, making her fall asleep. When Kalnagini was about to bite Lakshinder, she saw that Behula had committed no sin for which she might be given such a harsh punishment. Hence, she used her large tail to smear the parting of Behula's hair with oil from a lamp, which was considered sinful for a newly wed woman. When she bit Lakshinder, he shouted aloud and woke Behula up. Seeing Kalnagini slithering out, she furiously threw the jaanti at her, cutting off the lower part of her body. Kalnagini bit Lakshinder on instruction from Devi Manasa. To bring her husband back to life, Behula sailed with her dead husband in a raft towards the heavens. Although she faced many dangers during her incredibly long and arduous journey, she eventually reached heaven and pleased all the gods with her enchanting dance. The gods promised to resurrect Lakshinder, provided she would get Chand Sadagar to provide anjali to Manasa. Desperate to save his only surviving son, Chand finally gave in and gave anjali to Manasa by his left hand. Manasa, having attained the position of a goddess in heaven, brought back to life Lakshinder as well as the other six sons of Chand. ==Another version==
