Hinduism presents a challenge to the "Divine vs. pagan religion" dichotomy. A comparison of trends in worship and trends in Essence flow make it fairly clear that Essence from Hinduism is heading towards Heaven. However, there are also some very powerful ethereal Hindu deities in the Marches: the chief three are Brahma, Vishnu, and Shiva. Their exact power is unknown, but some estimate that they're a match for some younger Superiors.
It's a matter of debate why these deities survived the Purity Crusades. For whatever reason -- lack of support, lack of time, or whatever it was -- Uriel never sent his forces into India.
