The 'Brahma Kumari World Spiritual Organization', or 'World Spiritual University', known in India as 'Prajapitha Brahmakumari's Ishwariya Vidyalaja', was founded in 1937 in colonial British India, by the diamond trader Dada Lekh Raj. His devotees call him Brahma Baba. They claim Raj was a manifestation, others might say 'avatar', of the Hindu God Shiva. Though Raj is dead now, the devotees at Mt Abu in India claim still to receive his channeled messages from the hereafter.
They expect Brahma Baba's return soon. Then, a destructive, but purifying fire will supposedly end the old 'Kali Yuga' era, and bring about a new Golden Era; in which the spiritual elite of Golden Souls (the Brahma Kumaris) will rule the world.
Devotees should be celibate, as sex is allegedly the great enemy of the soul. With a 'fifty points chart' devotees must count, whether they are thinking about Baba enough, and whether their thoughts are pure enough. Negative ideas [critical of the organization's leadership] are said to gobble up energy and to poison the atmosphere.
Ex-devotees complain about anti-women attitudes, and autocracy. New devotees often join the movement after supposedly non-religious introductory courses in 'Positive Thinking'. In followup courses, Baba enters the picture.
