Sri Satya Naranaya katha (narrative) comes from the Skanda Purana, Reva khanda. Suta Maharsi is the one narrating these account to Saunaka Muni, in Naimiṣāraṇya to the rishis who were performing a 1,000 year yajna for the benefit of mankind led by Śaunaka.
In the stories characters who ignored their promise to perform the puja after their wish had been fulfilled suffered as a result. Therefore, one is to deduce that one must stick to the promise given to the Lord in exchange of the desire fulfilled by his grace.
One is not to ignore or forget the Lord’s Grace.Prasāda is symbolic of God's Grace which Kalāvatī ignored as she learned of her husband’s safe return. One can understand her eagerness in wanting to be re-united with her beloved, but one must understand that if one forgets to be thankful for gifts received from the Lord, one would have to go through another test until one remembers to remember.
Satya means “truth” and narayana means, “The highest being” so Satyanarayan means “The highest being who is an embodiment of Truth”.
Hindus throughout perform Sri Satyanarayan Vrat for the divine blessings of health, wealth, prosperity, opulence, education; relief from troubles and sickness.
