According to legends, King Manan Singh was the king of Hathua. He considered himself to be the greatest devotee of Durga. Because of pride, they did not consider anyone to be a devotee of mother. In this state, there was a famine in the state and people started craving for food. Thaavu was a true devotee of the devout goddess mother in Thawe. According to the legend, Rahasu used to eat grass in the day with the grace of the mother and she used to get food from the night, due to which the people there started receiving food, but the king did not believe. The king asked Rahu to call the mother a croaking and call the mother. Rahushu often prayed to the king that if the mother comes here then the state will be ruined, but the king does not believe. On the prayer of Rahushu, all the buildings of the king who reached here, along with mother Kolkata, Patna and Ami, fell and the king died. Where the mother visited, there is a grand temple and there is a temple of Rahasu Bhagat at a distance. It is believed that those who come to see the mother also visit the temple of Rahasu Bhagat, otherwise their worship is considered incomplete. There is still the ruins of Manan Singh's buildings near this temple.
Fort Temple
The temple is in the structure of a fort that is surrounded from all sides, on the bank of the River Ganga. It lies in the flood-prone district of Saran and it is very near the Ganges. The Ganga takes a curb at this point going to South. The image of the Ganga at this point is Lingvat. Even during a flood, the Ganga never touches the fort. The entire structure of Temple is on debris. During 1973 the then Director of the Department of Archaeology of the Government of Bihar Sri Prakash Chandra excavated and found a wall made of bricks used during the Pala Dynasty. In the worship of Sakti an equidistant triangle has the same importance as Saligram for Lord Vishnu and Shiva Ling for Lord Shiva. The centre of the triangle is called Prambika Or Ambika. Surprisingly the distance of the three Shiv Temples are equal and if you draw an imaginary line connecting the three Shiva Temple it will an equidistant triangle with Ambika Asthan Ami in the centre. This shows the importance of Ambika Asthan Ami. This place is also said to be the same place where King Surath & Samadhi Vaishya, performed AGYA for three years and got the desire fulfilled with the grace of Divine mother. It is also said that the place Digwara was originally called Drigdwara. This was the main gate of the palace of Daksh Prajapati where he organised Yagna. The palace was destroyed by Maa Sati. There are many other places claiming the same importance but in view of the fact that the incidence of Sati Sacrifice took place in Adi Satya Yuga and has been repeated in every Satya Yuga such claim and counterclaim can not be denied. There is a belief associated with the temple is that one who worships over here, his/her wishes get fulfilled by the Goddess. Hence in Dusshera, worshippers from different places gather here to obtain the divine blessing.
As the temple is devoted to Goddess Ambika, Navratri is celebrated and there is one small village fair also organised by the local people of Aami village.
Shivratri
is organised with quite a lot of excitement among the local people, as this was the place where the marriage ceremony of Shiv and Sati took place.
Shiv-Vivah
This festival is of high importance being organised in the manner of the marriage of Shiv and Sati. From one side the bride prepares and from one side comes the groom; according to this a fairy marriage ceremony is organised in a holy Hindu way.
