Siva is the Source of all the Scriptures

Siva is source of all literature (ola leaves, temple carvings, stone edicts, etc)

Image of Satguru Sivaya Subramuniyaswami
Through temple worship, the three worlds become open to one another, and the beings within them are able to communicate. By means of the mystical arts of puja, the worlds act in concert, and prayers are received.
