This historic shrine, Sri Gurdwara Guru Tegh Bahadur or Damdama Sahib at Dhubri in Assam was built in memory of the visit of Guru Nanak. Hence it has great importance for Sikh community. Guru Tegh Bahadur established this Gurdwara during his 17th century visit to the area. Sikh devotees from all over India and the world assemble in this Gurdwara every year in the month of December to mark the martyrdom of Guru Tegh Bahadur with due solemnity and ceremony. Sikh devotees call this festival Sahidee Guru Parav.
When Raja Ram Singh son of Mirza Raja Jai Singh was deputed by Emperor Aurangzeb to crush the revolt of King Chakradhwaj Singh of Kamrup (Assam), he called on Guru Tegh Bahadur at Dhaka and requested that he accompany him on his expedition to Assam. His request was accepted by the Guru who had planned to visit Assam in order to revive the religious centre built to commemorate the visit of Guru Nanak in the land of magic and beauty. Together Raja Ram Singh and Guruji, marched along the river Dhubri and Brahmaputra and reached Kamrup early in February, 1669 A.D. Guru Tegh Bahadur camped at Dhubri while Raja Ram Singh camped at Rangamati. The Imperial Army was confident of its strength but was not as yet sure whether the holyman with them would be able to destroy the evil effects of magic and witchcraft of the Assamese. Just across the river the Assamese were unnerved by the superior numbers of the Imperial Army but they were confident that the supernatural powers of their magicians backed by their tactful resistance would keep the attackers at bay.
The magic Assamese women with their tantric paraphernalia began reciting mantras of destruction in their encampment directly across the river of the camp of Guru Tegh Bahadur. But all their magic failed to harm the great Guru. The magicians were too confident about their ability to destroy any human being. From across the river they hurled a 26 feet long stone, which came arcing across the sky like a missile and struck the ground, near Guruji's camp, so hard that nearly half of its length was embedded in the ground. It can still be seen in the same position.
Their magic comes to an end
When their missile of stone failed to harm the holy benefactor, the magician next flung a tree, which fell very close to the Guru's camp without causing injury to any one. Then, as Guru Tegh Bahadur took his bow and aimed an arrow at the altar of magic all of their magic and sorcery came to a sudden end. The magicians realised that superior powers had completely deprived them of their magical strengths and stilled their willpower, so they crossed the river to the Guru's camp and begged forgiveness for having offended him. They told him that they were fighting only to repell the foreigners who had come to enslave them.
Guru Tegh Bahadur assured the magicians that he would work to bring peace between Raja Ram Singh and the Ahom King, for which, a change of heart was necessary on both sides. Consequently, he advised Raja Ram Singh to achieve his rulers objectives through peaceful negotiations and not to fight unless he was attacked. The rest of the story is a part of the history as to how he succeeded in patching up the differences between the Imperial Commander Raja Ram Singh and the Ahom King of Assam. The grateful Ahom King invited Guruji to the Kamakhya shrine, where he was honoured with great respect.
