Arti Varma's daughter, Meera Varma, who survived the attack, is a nationally recognized mental health advocate and TEDx speaker, according to her personal website. She has worked alongside prominent figures, including Oprah Winfrey, President Joe Biden, Jill Biden, Kamala Harris and U.S. Surgeon General Vivek Murthy.
