Hindu history reveals a long tension between the hierarchy of purity imposed by priests and the doctrine of atma revealed by the poet-saints. The latter doctrine led to the ritual of the gods going out on processions regularly, stepping out of the temple on palanquins and chariots, to meet those communities who were not allowed inside the temple. It also led to many doorkeepers being made to look very much like the deity enshrined within the temple. This was to assure those being excluded that while humans may exclude humans, God excludes no one.
