The puja is performed from the Skanda Purana. The story is narratedby Sutha Puranik, a rishi, who is narrating the story to a group of rishis performing a thousand year yajna for the benefit of mankind. The rishis asked Sutha Pramanik as to how an individual with ethical andlife-affirming desires could have his desires fulfilled. Sutha further explained that this same question was alsoasked by Narada, another great rishi and the son of Lord Bramha or the creator. Narada is one famous character that pops up all through Vedic mythology as an instigator who could set everything in motion. He had the finest comic sense and mischief.
In this tale, Narada is shown travelling the entire universe before coming to the Earth, or Bhuloka. On earth, he found that many people have been suffering as they were living through their karma from the past life. That filled him with compassion for the ones suffering and he went to Lord Vishnu and asked if something could be done to help these people. Narada and Lord Vishnu were great friends. Vishnu, in turn, asked Narada for suggestion. Narada then explained that there’s a puja that can be performed by everyone to eliminate sufferings from their life; it is called the Satyanarayan puja. He also added that this puja can be done by everyone; it is not necessary to have a priest, at any time without having to wait for an auspicious moment. Apart from this, there are other stories as a part of the Satyanarayan Katha, which makes this ritual a celebration.
Satyanarayan Pooja is the best way to seek blessings of Lord Vishnu.It is performed before and/or after the fulfillment of one's desires.It is also performed every year, to maintain the general happiness, prosperity and well being of the family.
Satya Narayan is the form of Lord Vishnu. The Lord in this form is considered an embodiment of truth(Satya). Satyanarayan is worshipped at home with family and friends by reciting the miraculous story of Lord Satyanarayan.

This story was originally told by Lord Vishnu himself to Devrshi Narad forthe benefit of mankind. Satyanarayan Pooja can be performed on any day in consultation withpriest(Panditji).However,the best day to perform this Pooja is on the day of Poornima (full moon day) or Sankranti.
Performing the pooja in the evening is considered more appropriate. On theday of the pooja, the devotee has to fast.On this auspicious day friends and relatives are invited to enjoy the Prasad (holy food).
