Synopsis Open boundaries provides a new perspective on Jainism, one of the oldest yet least studied of the world's living religions. Ten closely focused studies investigate the interactions between Jains and non-Jains in South Asian society, with detailed studies of yoga, tantra, aesthetic theory, erotic poetry, theories of kingship, Goddess worship, temple ritual, polemical poetry, religious women, and historiography. Viewing the Jains within a South Asian context results in a strikingly different portrait from the standard models represented in both traditional western and Indian scholarship.
