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
God Siva knows in infinite, all-abiding, loving superconsciousness. Siva knows from deep within all of His creations to their surface. His Being is within every animate and inanimate form.
—Gurudeva
