Summary: From around 1250 onwards, Hinduism and Buddhism in Cambodia and Siam were influenced by Indian culture, with Brahmins performing state ceremonies and astrology, reflecting Indian dominance over Chinese influence. In Nepal, Buddhism faced decay and corruption but persisted due to protection from outside invasion, preserving Sanskrit literature yet becoming integrated with Hinduism. Hindu dynasties in Java and Cambodia coexisted with Brahmanic hierarchies, with Siva worship predominating. The Champa civilization featured early Buddhist inscriptions, possibly indicating an Indian dynasty. Hinduism remained resistant to European and Islamic influences in India, with Islam absorbing into Sikhism, but minimal impact on Hinduism. Social changes like caste evasion and opposition to child marriage have occurred, but European influence remains limited. Buddhism, influenced by Western ideas, faced challenges, while Hinduism has shown resilience and continuity despite cultural changes and external interactions. The philosophical concept of rebirth and the nature of the soul in both Hinduism and Buddhism offer unique perspectives on life's purpose and existence, differing from European conceptions of the soul and immortality.
