The initial religious systems of the Sundanese were animism and dynamism with reverence to ancestral ("karuhun") and natural spirits identified as "hyang", yet bears some traits of pantheism. The best indications are found in the oldest epic poems ("wawacan") and among the remote Baduy tribe. This religion is called "Sunda Wiwitan" ("early Sundanese"). The rice agriculture had shaped the culture, beliefs and ritual system of traditional Sundanese people, among other the reverence to Nyai Pohaci Sanghyang Asri as the goddess of rice and fertility. The land of Sundanese people in western Java is among the earliest places in the Indonesian archipelago that were exposed to Indian Hindu-Buddhist influences. Tarumanagara followed by Sunda Kingdom adopted Hinduism as early as the 4th century. The Batujaya stupa complex in Karawang shows Buddhist influences in West Java, while Cangkuang Shivaic temple near Garut shows Hindu influence. The 16th-century sacred text Sanghyang siksakanda ng karesian contain the religious and moral rules, guidance, prescriptions and lessons for ancient Sundanese people.
