Philosophically and in relationship to Srila Prabhupada's teachings however there are actually only TWO scenarios, for scenarios 1 and 3 above are actually the same since they both accept that the role of the diksa guru in the life of the disciple as absolute. In fact scenarios 1 and 3 are identical with only the identity of the diksa guru changed. Since the 'ritvik' system is not a different 'guru' system but merely a system that keeps Srila Prabhupada as the diksa guru. Indeed in relationship to Srila Prabhupada's teachings it is actually the 'Bombay proposals' which are 'deviant'. This is the purpose of diksa, or initiation.
Initiation means receiving the pure knowledge of spiritual consciousness.
Diksa actually means initiating a disciple with transcendental knowledge by which he becomes freed from all material contamination. Diksa is the process by which one can awaken his transcendental knowledge and vanquish all reactions caused by sinful activity. A person expert in the study of the revealed scriptures knows this process as diksa. It is the spiritual master who delivers the disciple from the clutches of maya by initiating him into the chanting of the Hare Krishna maha-mantra. This is the purpose of Diksa or initiation.
