The Adhyatmik Vishwa Vidyalaya ashram in Rohini in New Delhi is a fortress. The four-storey building houses 200 women and a dozen men, but no one can say for certain. Each window is blocked by thick iron bars and wrapped in blackout sheets. The roof, where the women might dry clothes, is obscured by thick green tarp. Outsiders aren’t allowed beyond the lobby, and AVV members don’t leave without escorts. The underground parking ensures that even during CBI raids—at least three in nine years—the neighbours would not know.
