Mahalakshmi Vratham is different from Varalakshmi Vratham.The greatness of Mahalakshmi Vratham was explained to Yuthisthira by Lord Krishna. Yuthisthira wanted to know about a Vratham with which he can get back all that he had lost including property and wealth. The importance of the Vrata is also mentioned in the Bhavishya Puranan. The main ritual during the Vratham is abstaining from non-vegetarian food, waking up early taking bath and praying to Goddess Lakshmi for prosperity.
It is said that Lakshmi will enter the house of anyone who thinks of her and bless them. There are many festivals in the year dedicated to Goddess Lakshmi. Among them, Mahalakshmi Vratham is considered very auspicious because it is marked by strict observance of certain practices and austerities.
It is a very auspicious day to perform Lakshmi Kubera Homam on this particular day
