Sita Samahit Sthal (Sitamarhi), the holy place of Sitamarhi is situated almost midway between Allahabad and Varanasi. Just beside the national highway No. 2 and also connected with Allahabad and Varanasi railway line with Jungiganj, the nearest railway station, it is a well known Hindu pilgrimage and a good tourist spot with a lot of tourists almost throughout the year.
It is said that this temple is the place where Mata Sita went into the earth when she willed it while she was living with Saint Valmiki in the forest of Sitamarhi. It was Saint Valmiki who wrote Ramayana. According to Ramayana when Lord Rama came to Maa Sita (her wife) to ask her to come with him. According to Ramayana and other sacred books of Hindu dharma, when Lord Rama returned from the grand victory on Ravana the powerful king of Lanka. After becoming the king of Ayodhya a big yaga was held by Lord Rama and the horse of that grand yagya was released from Ayodya, the horse was to move in any direction or in any kingdom, the king of that kingdom should have to declare Rama as his Emperor. When the horse was wandering in the jungle of now Baripur village of Bhadohi district, the two sons of Maa Sita captured the horse according to the declaration that was tagged on the forehead of the horse. All the great warriors of Lord Rama Including Laxman, Bharat, Saturghna, Sugreev, Nal-Neel were defeated in the fierce battle between the two Lav ahd Kush the most powerful Hanuman was tied by them. At last the great Maharaja of Ayodya had to come to that place to fight the two children whom no one accepted ma sita and the saint Valmiki. No one knew that both boys are the prince of Ayodhaya and the son of Rama. When Rama came to the battlefield, all the holy souls of the three world comes to see the rare scene and Maa Sita also comes to Lord Rama and said with folded palm that she served with Her all efforts and love and it was time to end this human life (note human life because they were God and Goddess) after She asked Her mother (the earth) to take Her into her lap. She left behind Her two sons Luv and Kush whom Lord Rama took to the Great Ayodhya empire.
