Ronit Plank was six years old when her mother announced she was leaving the family to visit a guru on an ashram in India. The guru's name was Bhagwan Shree Rajneesh and his teachings were a mix of dynamic meditation, Hinduism, psychotherapy, the human potential movement, and lots of sex. Then, the colony fell apart amidst charges of fraud, bio-terrorism and an assassination plot. Bill Radke spoke with Ronit Plank about her new memoir, "When She Comes Back," how her mother's search for answers affected the family.
