India is mentioned in many ways in Talmud and clearly our sages had extensive trade with India, for example Kohen Gadol's garments and Ketoret ingredients see Mishnah and Talmud dealing-with-indian-reality-150-500-ce.
Rambam's brother David was a serious trader in India and died in shipwreck in the Indian Sea, losing Rambam's money (here). I presume that Indian tradition and rituals did not change over the last millenium. However in the current debates over Kosher wigs (see NYTimes) many Orthodox Rabbis in Israel forbid wigs exactly for this reason (idolatry). I also found an interesting article, stating that
The Jerusalem meeting [with the Chief Rabbinate of Israel, the American Jewish Committee, World Council of Religious Leaders, and others] concluded with a landmark declaration that Hindus worship ‘one supreme being’ and are not really idolatrous.
What was the Talmudic and Rambam view on Hinduism (from idolatrous point)?
