After Golkar won the elections in 1972, Djamin Ginting, a leading BPAMSL figure proclaimed BPAMSL as a movement within Golkar, adopting Islam as his religion, while Indonesian National Party supporters rejected this. With BPAMSL no longer a united force for the practice of Pemena, and Pemena itself no longer a uniting force in the Karoland, and with all Indonesians required to follow one of the religions of Islam, Protestantism, Catholicism, Hinduism and Buddhism, or risk writing 'without belief' on their identity card, the board members of BPAMSL met with a wealthy Indian man from Medan and determined that the traditional religion was in fact an expression of Indian Hinduism, and that it had been founded by a 'Bagavan Bṛgu', from which had been derived the alternate name for the Karo beliefs 'Perbegu' (followers of 'begu' (in Karo, begu is a spirit or ghost)), the existence of Indian-originating Karo marga names and similarities between Karo ritual and Indian Hindu ones all proving this. Thus the Association of Karo Hinduism (PAHK) was proclaimed.
