Hanuman Puja is performed a day before Diwali. This is a famous event in some states of India especially Gujarat. The day of Hanuman puja also coincides with the day of Kali Chaudas when Goddess Kali is worshipped. As per the beliefs, the bad spirits are highly powerful during the night of Kali Chaudas. Hence the performance of kali Chaudas puja is advocated in order to drive them away and gain a tremendous relief in life.
Why perform Hanuman puja on this day?
On the day of Kali Chaudas, Lord Hanuman is worshipped in order to gain strength to fight the negative forces and evil spirits. Hanuman puja on this day is believed to protect people from all kinds of dangers and misfortunes and fill the homes with luck, prosperity and happiness.
Hanuman Puja reference in Ramayana
Lord Sri Ram returned to the city of Ayodhya victoriously after defeating the demon Ravan and rescuing Mother Sita from his captivity. The citizens of Ayodhya organized a grand welcome to invite Rama to the portals of their city after a long period of fourteen years. This day marked Diwali celebrations. However, in honoring the great contribution made by Hanuman to win over Ravan, Lord Sri Ram advised that hanuman puja is performed before his puja. Hence Hanuman puja is done a day before Diwali.
At the Hanumangarhi temple located in the city of Ayodhya, this day is also celebrated as Hanuman Jayanti (the birth day of Hanuman). However, this event falls on a different day as per the other Hindu traditions.
