Religious tolerance

It was interesting to read that:

"Cambodia was an experience in religious tolerance. Hinduism and Buddhism have fought each other ceaselessly over hundreds of years, with Buddhism finally triumphing. Yet, in each war, where one faith attempted to supplant another, there was tolerance of one another."

I wonder what this means in terms of the faith of the Cambodian people? Is their belief a mixed hybrid of the things said in various sacred texts? Have they replaced the sacred words with their own interpretations? Or are some people more faithful to certain texts compared to others?

I would be interested to understand further what people believe.
