Indentured labourers could not easily maintain religious and caste distinctions in the plantations. They tried to take part in their rituals faithfully and took comfort in religious texts.

The epic Ramayana was especially significant for the Hindu migrants. Its themes of exile and triumph of good over evil resonated with the workers who struggled to survive in foreign countries. For successive practising ones religion was a way of showing solidarity with one's community. It also gave Biharis a space to celebrate their identity. This is possibly the reason why diasporic communities have built temples and mosques and founded religious organisations.
