Sharat Purnima falls on the full moon in Shukla Paksha of the Ashwin month as per the Hindu calendar. It is believed that on this night the rays coming out of moon contain nectar or Amrit in them and they have the power to heal any wound and fill the life of an individual with prosperity.
On this day, people must worship the idol the Maha Lakshmi in the morning. In the night, the Prasad of ‘Kheer’ made of pure cow milk must be offered to the God and kept in the moon light overnight and must be consumed in the morning. It is said that by doing so, the kheer gets the nectar present in the moon rays and by consuming it, one gets free from all diseases and blessed with peace as well as prosperity.
The devotees should make offering to the Lord of Moon too. It is very auspicious to donate bronze bowl filled with ‘Ghee’ along with dakshina to the Brahmins on this day. The Hindu mythology also says that Shri Krishna did the Rasleela on the same day. Hence, in Brij and Vrindavan this day is celebrated with great zeal and enthusiasm. The festival is also popular by the name of ‘Rasotsav’ or ‘Kaumudi Mahotsav’.
Kojaga Vrata is also observed on the full moon night of the Ashwin month. It is believed that on this festival, Goddess Lakshmi roams in the night to check who are awake and bestows the wealth to the one who are awake and worship Goddess Lakshmi overnight.
In this fast the idol of Lord Indra riding a elephant along with Goddess Lakshmi is worshipped. In the evening, diya or lamps of ghee are lit and placed in the various corners and rooms of the house and also in the Tulsi plant. Next morning, after taking shower Lord Indra must be worshipped again to get blessings. Donate kheer, brass lamps, and clothes to the Brahmins on this day.
The conventional story of this fast spins around a poor Brahmin and his wife. This couple was exceptionally poor and the wife insulted the Brahmin each day. She frantically needed to be rich and even incited her spouse to take cash. Tired and baffled by her disposition and activities, the Brahmin headed off away to woodland where he met the ‘Nagkanyas’. That day was “Purnima” of “Ashwin” month along these lines the “Nagkanyas” exhorted the Brahmin to do “Kojagarvrata” and mollify Goddess Lakshmi. The Brahmin finished so and Goddess Lakshmi offered him with fortune and fortune. With the endowments of the Goddess, his wife’s state of mind excessively changed and the couple existed euphorically ever after. From that event, this convention of “Kojagarvrata” came to be hugely popular among the Hindu people.
One must also chant the Shree Sukta, Lakshmi Strotra and perform a havan to appease the Goddess Lakshmi.
