Jainism’s rejection of God does not entail
rejection of prayer and worship, more precisely termed contemplation. But
of all beings, including the gods and the saints, only liberated souls or
Tirthankaras made perfect are worshipped. Even they are not appealed to
for help or mercy; they serve more as an inspiration to those still
struggling for freedom and perfection.
That is the theory, The practice is very
different. Many of the Jain laity pray to Hindu gods for help, many Jain
temples house images of Hindu deities, and many Jain festivals incorporate
Hindu customs.
