The white-clad people you’ll see around town are members of the Brahma Kumaris World Spiritual University , a worldwide organisation whose headquarters are here in Mt Abu. The university’s Universal Peace Hall , just north of Nakki Lake, where free 30-minute tours are available, includes an introduction to the Brahma Kumaris philosophy (be prepared for a bit of proselytising). The organisation also runs the World Renewal Spiritual Museum in the town centre.
