The story of Jai Jagannath is based on the ancient scripture Lakshmi
Puran. The untouchables were not allowed to pray, worship and do
rituals to God in the ancient ages.
Sriya - one of the important characters in this story dares to pray and worship and wins over the support of Goddess Lakshmi.
The
real drama begins when Lakshmi is separated by Lord Jagannath at the
behest of his brother Balram (Balabhadra) because she ends
discrimination on earth by encouraging even untouchables to conduct
rituals and worship.
As Lakshmi moves out of Jagannath's household
both Jagannath and Balram undergo immense suffering so much so that
they have to starve without water and food. The curse of Lakshmi had a
severe impact on both the brothers that for 12 years they had a tough
time.
Soon they realise the importance of Lakshmi and were keen to bring her back to their abode.
Lakshmi returned to Jagannath's abode on one condition that there will be no discrimination of caste and creed on earth.
This
unique story highlight the fact  that for God everyone was equal
besides it reflected the reforms and progressive stance of Gods from
the ancient times.
Only in the end through Narad it is revealed
that Jagannath to end castism and discrimination had himself "set up"
these series of events which highlighted the social message besides the
strength of true spirituality.
