It's the story of a boy who finds enlightenment by experiencing religious hipocrisy and dogmatism. Dnyaneshwar liberated the "divine knowledge" locked in the Sanskrit language to bring that knowledge into Prakrit (Marathi) and made it available to the common man.
This is a Puranic tale, which, by all accounts, was a grand mythological spectacle full of miracles and fantasy scenes with special effects. Chitnis played the god Shanker, and Suresh played the sage Narada.
