Read the following paragraph and underline the topic sentence. 　Importantly, the Hindu （印度教) and Buddhist influences from India were not imposed by conquest or foreign domination (管辖). The influence was more apparent than real. Beneath the surface, the Indian religious symbols and rites were freely adapted to express the animist (泛神论) beliefs and ancestor worship of Austronesian (南太平洋岛屿) culture. Outside the nobility, life went on for the general population much as it had for thousands of years. The Sanskrit (梵文) script, for instance, does not appear to have been applied as an aid for commerce. With the notable exception of Bali, the Indian caste system was not imported. The social organization continued to follow the traditional kinship system of Austronesian society.
