BKs believe that not only does " God " enter her body and possesses or takes complete control over her senses including the power of vision and speech but that " God " comes in a combined form with the soul or spirit of Dada Lekhraj, also known as Brahma Baba. This combined form is known as Bapdada, literally " Grandfather and Father ".
This process of spirit channelling is said only to happen at the BKWSU headquarters called Madhuban in Mount Abu, India and for a short time each year. BKs internationally make efforts to attend Madhuban in order to witness " Baba's Season " and " meet God ".
