mahakumbh

The new moon of Magh Month is called Mouni Amavasya. This is Mahavrat based on Yoga. According to the belief that the goddess is present in the holy meeting on this day, hence Ganga baths have special significance on this day. This month has also been called pure month like Kartik. On this river, on the Ganges, the Karnabhakta people consume the Ganga by making a hut for one month.

Mythological reference.

Another story also comes in the context of bathing in the Sangam, that is the story of Sagar Manthan. According to the legend, when Lord Dhanvantri came out with Sagittar Manthan in the form of Amrit Kalash, at that time, the tension started for the nectar in the deities and fight started to take the Amrit , and some drops of nectar dropped at Allahabad, Haridwar, Nasik, and Ujjain. This is the reason how you get the benefits of soul purification by bathing on the rivers here.

If this date falls on Monday, then its importance increases. If there is a Monday and a great mahakumbh also there,  then its significance becomes multiplied. It is said in the scriptures that in the Sat Yuga that the virtue that you get by tapa, by devotion to God in Dwapar, by knowledge in Treta, by donation in Kali Yuga, but Sangham Bath in Magh Month will always be auspicious in every age. On this date, after the bath in holy rivers, you should donate food, clothing, money, cattle, land, and gold whatever you desire according to your wishes. On this day 'til' donation is also said to be excellent. This date is also known as Mouni Amavasya, which means, Moun Amavasya. Since this fast one has to follow the silence throughout the day, therefore it is called fast based on yoga.  It is best to keep silent on this date If possible, do not take any bitter word from your mouth. This date is the worship of Lord Vishnu and Shiva Ji both. In fact, both Shiva and Vishnu are the same, who take two forms for the welfare of the devotees, this is mentioned by God Himself. On this day in Peepal, worship peepal tree and donate deep.  Those who are unable to fast on this day,  eat sweet food.
