Once Brihaspati Dev and Brahma Dev were having some conversation when Brihaspati Dev asked Brahma Dev that “Please tell me why Navratri fast is observed and Navratri is observed during the Shukla Paksha of Chaitra and Ashwin months? What are its benefits to humans?” What is this fast and how should it be observed? Please explain in detail?”
Hearing this profound question of Brihaspati Dev, Brahma Dev replied, “O Brihaspati Dev, you have asked a question which is highly beneficial for all living beings. In fact, those who contemplate Durga, Mahadev, Surya and Narayana with devotion are blessed with their wishes. All wishes are fulfilled by this fast. This fast has the power to fulfill all wishes. Those who wish for a son get a son, those who wish for wealth get prosperity, those who wish for knowledge get knowledge and those who wish for happiness get happiness.
Moreover, this fast has the ability to heal the ailments of the sick. It removes all troubles, brings prosperity to homes and blesses married women with a son. It frees individuals from their sins and fulfills their heart’s desires. On the contrary, those who are negligent in observing this Navratri fast often find themselves suffering from sorrow, suffering, illness, childlessness, poverty and deprivation. They wander aimlessly, are tormented by hunger and thirst and lose their sense of purpose. As for virtuous women who do not observe this fast, they may experience a lack of marital happiness and face many hardships. If one is unable to observe the fast for the entire day, they should eat once a day and listen to the story of Navratri Vrat with their loved ones for ten days.”
“O Brihaspati Dev! Allow me to narrate the story of a person who observed this great fast in the past. Listen to the story carefully. Thus, after listening to the words of Brahma Dev, Brihaspati Dev replied, 'O Brahma Dev, you are the well-wisher of humanity, please explain the history of this fast. I am listening carefully and want your guidance and blessings.'
