ISKCON gurus and Swamis
ISKCON guru is permitted to initiate disciples in the system that is being used in International Society for Krishna Consciousness; this ISKCON Guru System has undergone a considerable evolution and reform since its beginnings in 1970s. Upanayana as a traditional "sacred thread ceremony" of the Gayatri Mantra, commonly known Hindu Samskara, is complimented by Pancaratric mantras of the Gaudiya Vaishnava sampradaya and follows the principal initial nama initiation ceremony, refereed respectively as brahmana diksa and Hari nama diksa ISKCON is seen as an extension of the Gaudiya-Vaishnava tradition and thus participates in the disciplic succession from Caitanya Mahaprabhu. In most India traditions spiritual authority rests in one person, or acharya, head of a monastery or a whole sampradaya.
ISKCON is sometimes described as the "first global Vaisnava movement" and is different. ISKCON is a multi-guru organization that places the ultimate managerial authority in its Governing Body, a group rather than a single person. Current ISKCON Guru System is developed by the group of leaders, Governing Body Commission, (GBC), the managerial authority of the International Society for Krishna Consciousness.
ISKCON Guru system was originally initiated and put in place by ISKCON's founder, A.C. Bhaktivedanta Swami Prabhupada who organized and sometimes himself conducted initiations since early 1970s.
