From BrahmaKumaris.Info Encyclopedia
Following the visions and possession by the spirit the BKs name as "Shiva Baba", Dada Lekhraj's body was used in order to express a message to humanity and teach what became to be known as Raja Yoga. Followers, known as his "mouth born progeny", believe that Lekhraj Kripalani is God's only direct medium or instrument.
For the first 20 years of the movement's existence, Kripalani was called Prajapati God Brahma. There was no God Shiva in their theology. Kripalani was considered by Prajapati-Brahma Kumari followers to be a reincarnation of, and about to be reincarnated again, as Krishna in a Golden Aged heaven on earth.
