There is a certain positive feel to this sort of approach:
In contrast to many monotheistic religions, there are no absolutes in Shinto. There is no absolute right and wrong, and nobody is perfect. Shinto is an optimistic faith, as humans are thought to be fundamentally good, and evil is believed to be caused by evil spirits. Consequently, the purpose of most Shinto rituals is to keep away evil spirits by purification, prayers and offerings to the kami.
