Overlaps in Jain-Hindu identities have included Jains worshipping Hindu deities, intermarriages between Jains and Hindus, and medieval era Jain temples featuring Hindu religious icons and sculpture. Beyond India, on Java island of Indonesia, historical records attest to marriages between Hindus and Buddhists, medieval era temple architecture and sculptures that simultaneously incorporate Hindu and Buddhist themes, where Hinduism and Buddhism merged and functioned as "two separate paths within one overall system", according to Ann Kenney and other scholars. Similarly, there is an organic relation of Sikhs to Hindus, states Zaehner, both in religious thought and their communities, and virtually all Sikhs' ancestors were Hindus. Marriages between Sikhs and Hindus, particularly among "Khatris", were frequent. Some Hindu families brought up a son as a Sikh, and some Hindus view Sikhism as a tradition within Hinduism, even though the Sikh faith is a distinct religion.
