 Even among Hinduism denominations such as Shaivism and Vaishnavism, the Hindu identities, states Leslie Orr, lacked "firm definitions and clear boundaries".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.
