Hinduism once spread missionaries but later stopped converting outsiders.

Evidence

Whether the Hindu religion was or was not a missionary religion has been a controversial issue. Some hold the view that it was never a missionary religion. Others hold that it was. That the Hindu religion was once a missionary religion must be admitted. It could not have spread over the face of India, if it was not a missionary religion. That today it is not a missionary religion is also a fact which must be accepted. The question therefore is not whether or not the Hindu religion was a missionary religion. The real question is, why did the Hindu religion cease to be a missionary religion? — Ambedkar, B R, Annihilation of Caste_ The Annotated…, 890

• QUESTION: Ambedkar poses but does not here answer why Hinduism ceased being missionary; worth chasing his subsequent answer in the text.
• XREF: Ties to the caste-sacralization history in this volume and to debates over Hindu conversion-driven demographics.
