Kamini had been a stage actress in Delhi during her college days from 1942 to 1945. She worked as a radio child artist with the name "Uma" in Lahore before the Partition, from 1937 to 1940. She said in an interview about whether she wanted to be an actress in her childhood: "I come from a very intellectual family. My dad, S. R. Kashyap, was a professor at Government College, Lahore and the President of the Science Congress. He'd written about 50 books on botany. Growing up, our family concentrated more on knowledge, but he never deterred us from doing anything we wanted as long as it was positive." Though she had no dreams of joining the film industry while being in college, she was a fan of actor Ashok Kumar. Once she said in an interview: "We were to perform for the war relief fund in college. Ashok Kumar and Leela Chitins were the chief guests. After the show we went to meet him. I thought of having some fun. As he stood talking to the students, I pulled his hair from behind."
