The father of Dhruvswamini is King Uttanapada, and her mother is Queen Suruchi. Dhruvswamini is a significant figure in Hindu mythology known for her devotion to Lord Vishnu.
There are several scenes in "Dhruvswamini" by Jaishankar Prasad. To know the exact amount, I would recommend purchasing the book online or at your local bookstore to read.
Dhruvswamini was the wife of Gupta Emperor Ramgupta and later was married to his younger brother Chandragupta II (Chandragupta Vikramaditya), the great Gupta Emperor.
