It was the Sheihnaq who bolstered all planets on its hood such was its dominance. Sheihnach was inseparable from Narayana. So when Vishnu incarnated as Sri Lank in traita Yog Shehnag also incarnated as Lakshmana the younger brother of Sri Rama in traita Yoga Lakshmana often complained because I'm younger brother Shri Rama always looks after me and tells me what to do in my next life I vowed to come back as the older brother so that I can take care of Vishnu as my younger brother
And I also know that it was that sheshnagh requested Vishnu, that in his next incarnation he wanted to be the older brother so that he can take care of Narayanas, his younger brother. And his wish was granted. And it was thus Bharama was born. And I am also aware of the story of Raivatiji, who became his better half. As finally they go and Brahma tells that Balram is the ideal match for Rewati
