• Keeping a fast and celebrating this Vrat with devotion increases reasoning power and analytic ability which is quite important for a student as well as a businessman.
• Though Budh Graha (planet) is generally considered as a beneficial planet, under certain circumstances it plays the role of a malefic planet. So, those born under the influence of strong Mercury, they should observe this Vrat to control their anxiety as well as indecisiveness.
• People afflicted by the ill-effects of the planet Mercury may suffer from highs and lows in relationships, nervous system disorders, hypertension, and lack of speaking, as well as writing skills. Observing Wednesday fast helps to overcome these problems with the divine blessings of Lord Budhdev.

Bhudhvar Vrat Katha (Wednesday Fast Story): A rich man named Keshav used to live in Varanasi. He was married to a beautiful and virtuous girl, Soubhagya of Allahabad. Once Keshav went to his parent-in-law's house to bring his wife. He asked his in-laws to bid farewell to Soubhagya. But her parents said, “dear son today is Wednesday, and traveling for any auspicious work is not done on Wednesday.” But Keshav did not listen to their repeated requests and told that he did not believe in auspicious or unfavourable things. After a lot of discussions, the parents of Soubhagya agreed to forcefully bid farewell to her.

Both started their journey in a bullock cart. After covering a short distance, Soubhagya felt thirsty. Keshav made her sit under a tree and went to bring water. When Keshav came back with water, he was surprised to see a man exactly like him sitting next to his wife. Soubhagya was also shocked looking at him because both were looking like a carbon copy.

Keshav asked that person “who are you and why are you sitting with my wife?” The man replied “gentleman, this is my wife and we are coming from my parents-in-law's house. But who are you to ask me a question like this?” Keshav started shouting and said “You must be a thief or a fraud. She is my wife and I had made her sit under the tree and went to bring water.” Hearing this, the man said “O man, you are lying. When Soubhagya was feeling thirsty, I went to bring water. I have already given her water. Now you must leave this place or else, I will call the nearby soldier and get you caught.”

Both started fighting. Seeing them fighting many people gathered there and started discussing the unexpected situation. Then a pleasant voice came from the heaven, saying “Keshav! You did not listen to the words of Soubhagya’s parents and made a forceful departure on Wednesday. This all is happening due to the rage of Budhdev.”

Keshav prayed to God Budhdev. He said “O celestial Lord, please forgive me. I have committed a big mistake; I will never travel on a Wednesday in the future.” Listening to this, the merciful Lord Budhdev forgave him. Immediately, Keshav’s duplicate vanished from that place and other people got puzzled looking at this miracle. Keshav and his wife happily started their journey towards Varanasi. They reached home safely and started observing the Bhudhvar Vrat. By the blessing of Lord Budhdev, their home was full of wealth and they lived happily forever. Since then, devotees started observing the fast of Wednesday with faith and devotion to fulfil their desires and to live a blissful life.
