A King once invited merchants from all over the region to attend a big crafts fair, assuring each that he would purchase whatever they could not sell. One blacksmith of limited intelligence brought an iron image of Sani (Saturn) to this fair, and since no one purchased it, the king's officers procured it and delivered it to his majesty in his inner apartments.

That night in a dream, the King saw a luminous female form - obviously a goddess - leaving his body. "Who are you?" he asked in some alarm. "I am Lakshmi, goddess of wealth and prosperity," the figure replied. "I cannot remain in the same place where Sani remains." The King saluted her respectfully but allowed her to depart.
Next emerged a male deity, Glory (Vaibhava) who, as he departed, said he cannot remain with anyone who has no prosperity. The King allowed him to go as well. Then departed, in order: Righteousness (Dharma), Staunchness (Dhairya), Compassion (Daya), Forbearance (Kshama), and a host of other virtues. When Truthfulness (Satya) prepared to leave, the King grabbed his feet and would not let him go, saying "I've never left you all these years, and you cannot leave me now."
All the other good qualities had been waiting outside the door for Truth to emerge, so that they might all seek shelter elsewhere. When he did not appear after quite a long time, Righteousness finally said "I have to go back; I can't exist without Truth." and so he returned. He was followed by all the others, in reverse order of their departure, and lastly, even Lakshmi returned. She told the King "It is thanks to your love of truth that you have all of us back, we could not resist. A fellow like you, who holds onto Truth, will never be miserable."

Sani is best known for bringing suffering and affliction. The meaning of the story is that if we spend a life clinging to truth, even Sani cannot drive out our good fortune for long. It needs to be said that Sani, when well placed in a horoscope, also brings good qualities, like making one a hard worker.
