How did Hindu mythology replace the traditional myths of Meitei Manipur?

Myths are an aspect of the respective religions.

It is obvious from history that Sanamahism, the ancient Manipur sect was replaced by Hinduism and is well known. Now, let me explain a short reason why and how the replacement happened.

From time immemorial till the early 18th century, the politically dominant people of Manipur, the Meiteis, we're ethno-religious, that is to say, the entire nation followed a single religion, Sanamahism, their ancestral religion.

However, during the reign of Pitambar Charairongba (1697 - 1709), he adhered to the Nimandi faith, a sect of Hinduism, as his family religion. Strangely enough, he neither persuaded nor forced his people to submit to his course. His son, Pamheiba, ascended the throne, and once he held the scepter of royal power, he began to demonstrate his power to his own people by forcing the entire Métai race to follow Hinduism.

There were revolutions and voices against him, but "the king is the law" and he managed to achieve supremacy. Those revolutionaries were either exiled or publicly tortured to terrorize civilians.

Traditional books written in the Métis alphabet, we were collected and burned.

This event is still known today as "Puya Mei Thaba", which literally means "burning of scriptures". It was an attempt to erase Mithaiism from the world and to impose Hinduism as the official religion.

The temples of the traditional Matthean faith were destroyed. Idols made of stone were crushed and those made of metal, especially gold and copper, were melted down.

A new Hindu pantheon was introduced into the kingdom. The traditional gods were replaced by equivalent Hindu gods, as were the myths.

At the same time, however, without the king's knowledge, the court scholars, who truly loved their ancestral religion, hid many of the books and sent them from the capital to the countryside without the king's notice.

In modern times, when Manipur was ruled by the British Empire, such books came out from their hiding places as they were no longer threatened by heirs from their own race.
