Observing the Brihaspativar Vrat with sincerity is believed to please Lord Vishnu and Brihaspati Dev, bringing prosperity, wisdom, happiness, and the fulfillment of righteous desires. In Vedic astrology, those with a weak Jupiter (Guru) in their birth chart are traditionally advised to begin this fast on a Thursday associated with Anuradha Nakshatra and observe it for seven consecutive Thursdays. The vrat is believed to help attract wealth, remove obstacles, and bless childless couples with children.

The Story of Brihaspativar Vrat

Long ago, there lived a wealthy merchant in a town. He was kind, generous, and always engaged in charity and good deeds. His wife, however, was extremely miserly and disliked giving charity. Whenever saints or wandering ascetics visited their home seeking alms, she would insult and send them away.

One day, Brihaspati Dev himself came to their house disguised as a holy sage.

The merchant was away, and only his wife was at home. Instead of welcoming the sage, she complained that she was tired of managing so much wealth and asked him to suggest a way to get rid of it.

The sage gently advised her to use her wealth for charitable and virtuous purposes, but she refused to listen.

Seeing her stubbornness, Brihaspati Dev said:

"If you truly wish to lose your wealth, then for seven consecutive Thursdays plaster your house with cow dung, wash your hair with yellow clay only on Thursdays, wash your clothes on Thursdays, ask your husband to shave on Thursdays, and consume meat and intoxicants on that day."

Having said this, the sage disappeared.

Believing his words to be genuine advice, the merchant's wife began following these practices exactly as instructed. Within just three Thursdays, the family's prosperity vanished, and according to the traditional legend, she eventually passed away.

The Merchant's Hardship

The merchant had a young daughter. Left with nothing, he wandered from village to village with her in search of a livelihood.

He began cutting firewood in the forest and selling it just to survive. Although he worked tirelessly, he could barely provide for his daughter, and this caused him immense sorrow.

One day, while weeping in the forest over his misfortune, the same holy sage appeared before him.

This time, the sage advised him to sincerely worship Brihaspati Dev, observe the Thursday fast, and listen to the Brihaspativar Vrat Katha.

Following the sage's advice, the merchant observed the fast with devotion. That very day, he received a good price for his bundle of firewood, and gradually his fortunes began to improve.

Forgetting the Thursday Fast

Before completing his seven Thursdays of fasting, one Thursday the merchant accidentally forgot to observe the vrat because he had been invited to a royal feast.

That very day, the queen's valuable necklace mysteriously disappeared.

Since the merchant and his daughter had arrived late at the palace, suspicion fell upon them. They were falsely accused of theft and imprisoned.

Faith Even in Prison

While in prison, the merchant remembered Brihaspati Dev and prayed for help.

The deity inspired him, saying:

"Nothing is lost. Even here you can continue observing the Thursday fast, recite the sacred story, and distribute jaggery and roasted gram as prasad."

Soon afterward, the merchant unexpectedly found two coins near the prison gate.

He first asked a woman to purchase jaggery and roasted gram for him, but she declined, explaining that she was busy preparing for her son's wedding.

Later, another woman arrived, grieving because her son had died, and she was on her way to buy a shroud for his funeral.

The merchant requested that she instead bring jaggery and roasted gram for the Brihaspati Dev worship.

She agreed, brought the offerings, listened to the sacred story, and accepted the prasad.

According to the traditional legend, when she offered the prasad and charanamrit to her deceased son, he miraculously came back to life.

Meanwhile, the woman who had ignored the merchant's request suffered tragedy when her son died after falling from his wedding horse.

Filled with regret, she later came to the merchant, apologized, listened to the Brihaspativar Vrat Katha, accepted the sacred prasad, and offered it to her son. By the grace of Brihaspati Dev, he too was restored to life.

The Merchant Is Vindicated

That same night, Brihaspati Dev appeared in the king's dream and revealed that the queen's necklace had never been stolen—it was still hanging on a peg inside the palace.

Realizing his mistake, the king immediately ordered the release of the innocent merchant and his daughter.

As an act of repentance, he honored the merchant with great wealth and personally arranged the marriage of his daughter into a noble and prosperous family.
