Zero may have originated in India, but it indeed was preserved and then transmitted further not by Indians. It's not hard to understand Peter BetBasoo's feelings toward Arabs/Muslims, but it's improbable that the Muslim progress stopped because "the Christian Assyrian community was drained of its population through forced conversion to Islam" and "it ceased producing the scholars that were the intellectual driving force of the Islamic civilization". Mr. Muhammad al-Khwarizmi (who's name is bared by the "Algebra") was a prominent scholar born in a traditional Persian family (not Arabian but Muslim nevertheless). I agree with mda (a post in the same level as yours) - it is unfair to reduce everything as just "sitting neatly between".

Concept of zero is not specific to Indian mysticism though. As well as its correlation with infinity.
