This needs to be brought to the attention of people who go to mandiras or Hindu temples in Bhārata (India). Hundi money is a form of a donation to the temple to help with temple operating expenses. Typically, there are hundi boxes situated in several places inside the mandira. There is a catch that many people don’t know about.
Hundi money does not go entirely to the mandira; in fact, only a minor amount is returned by the government to the mandira. This does not happen for any other religious group (Muslim or Christian, for example). How is this possible??? Article 26 of the Constitution of India is SUPPOSED to guarantee religious freedom and the ability to operate and maintain mandiras. But it is made possible initially through the Madras Hindu Religious Endowments Act in 1923 while still under British rule, and then later the Hindu Religious and Charitable Endowments Act XXII in 1959.
