श्री सत्य नारायण व्रत कथा!

Hindu mythology is replete with tales of the divine sage Narad Muni, who is called ‘Triloka Sanchari’ as he can move about in all the three mythical worlds. On one of his celestial trips, once when he visited earth, he witnessed rampant misery. Unable to find a way to relieve human suffering, he approached Lord Vishnu or Narayana and related to him the sad state of affairs on earth.
Vishnu said to Narad, “Let people observe the Satyanarayana Vrata in the evening of Shankranti or Purnima. Let them all hear the story of Satyanarayan Katha and all miseries will come to an end.”
Narad returned to earth and preached the glory of the Sri Satyanarayan Puja. Many observed the vow without taking any food during the course of the day and attained what they desired. As the legend goes, all were happy and prosperous.
