That is from very long time, mother is... Amba-devī. There is a... From Amba-devī, there is a big temple of Mother Durgā, Kālī, in Bombay. So this Amba-devī was pronounced by the Englishmens as Bamba-devī, and from Bamba-devī it has come to "Bombay." Actually, there is a big temple of Amba in Bombay.

And there is another place, or spiritual world, which is also called sanātana. In the Bhagavad-gītā you'll find, paras tasmāt tu bhāvo 'nyo 'vyakto 'vyaktāt sanātanaḥ (BG 8.20).

Therefore sanātana-dharma is not meant for any particular class or particular country or particular nation or community. No. It is meant for the whole human being, especially human being; otherwise, all living entities.
