With the grace of almighty Guru Nanak was born in Punjab province in 1469 AD. From his childhood, both by precept and example, he began to evince a highly refined and sublime spirit and started his mission to liberate the people from the priestly serfdom and superstitious bondage.

Nanak with a view to bring the people in the world to same level without any distinctions travelled in India, Asia, Middle East, Far East and some distant islands, wherever he went, he addressed the people in their language by virtue.

He was ever calm and cool, never lost his temper or resorted to harshness in response to cruel or unjust treatment. His preaching's were mostly confined to instilling in to the minds of the people, a spirit of meekness, humility, righteousness and surrender to the will of God.

The performance of such a long journey, when means of conveyance were so rare and difficult, especially in foreign countries professing different and antagonistic faith is nothing but wonderful. He travelled for sowing the seed of truth, prepared the people for a grand religious revolution to establish faith in one God. To remove the curse of untouchability, Guru Nanak, on his world wide tour, took with him two disciples a Hindu named Bala and another a Muslim named Mardana, both of low castes and treated them as brothers.

In 1504 AD on one of his four travels, Guru Nanak with his companions arrived at Rajmahal, Gaya, Baijnath, Bhangalpur, Sahibgang. The Raja Namdeo of Rajmahal requested Guruji to stay with him for some time and offered a garden called "Guru-Ka-Bag" (i.e. Guru's Garden).

On resuming his tour, guru ji travelled through Murshidabd, Krishnagarh, Shahzadpur, Sirajgunj, Devipur, Dacca and Dhanpur, at Dhanpur his companion Mardana felt hungry and went to the village in search but was enchanted and felt victim of witchcraft enacted by notorious women of that village, Guru could visualize with his divine power and dispelled the enchantment. On the other hand, the women in their turn were entangled in difficulty and their evil craft could not disentangle. Then they all in a body fell on the feet of Guruji and prayed for pardon. Sri S.K. Bhuyan thus writes in his "Background of Assamese Culture" when so late as 1500 AD. Guru Nanak, the first Guru and the founder of valiant Sikh nation, while reaching Dhanpur, on his world wide tour, near Dacca, has a bitter anguish of finding his brave companion Mardana, a Punjabi Musician accompanying him on his tour, converted into lamb before his eyes, by a women of this country, who could as reconvert the young man to his natural anatomical shape according to her personal and private needs of worldly desire. The Guru dispelled the enchantment and baffled all attempts of renew it…" The Guru addressed those women on the following hymn which is enshrined in Guru Granth Sahibji.

"In speech we are vitreous but in deeds we are vicious. In heart impure and black but outwardly we profess to be innocent. We enemy those sisters who serves their husband standing at the side of his bed for whole night," "They love their husband and enjoy pleasure in their company. You buy earth impregnated with salt and pepper only, but ask for mask into bargain."

In 1505 AD on his world wide tours, Guru Nanak the founder of Sikhism, came to Assam via Dhanpur near Dacca and stayed with Shrimanta Shankardeva, the greatest Vaishnavite reformer of Assam at the present site of Guruduwara, Dhubri Sahib, under Goalpara District (Assamese culture by S.K.Bhuyan.). Both discussed ways and means of saving the people from the clutches of Saktism and Tantrism, for including religious reforms, praying one God, eradication of the curses of black magic and black arts.

They also discussed how to save people from the curses of untouchability, hatred and to bring harmony, generating feeling of equality. Besides the place was rendered holy with the touch of feet of Guru Nanak (Max Arthar Macauliff. Page356). He then visited Rangamati, Jagigopa, Goalpara and stayed for some time at Kamakhya to deliver the message of one to the High priest which is still preserved there by the successors.

He thereafter visited Hajo, where he named a hillock as Bala Hill (Bala was companions of Guru) Mani-Kar-Nashwar Hills, stayed at Matsyadwaja. The River Savrat flow from Kamalake on the bank of which Guru Nanak built a temple naming the lake as Mardana Kund (Mardana was companion of Guru Nanak)

During the course of his journey, he also visited Sadya where Sri Krishna had married Rukmani. Brahmakund, where saint Parshuram had taken bath and regained saint hood , after fulfilling his vow to kill Kshatriyas with his axe. From this place he further traveled to Tibet, China, Japan, Java, Smatra, Philippines, Burma and re-entered India via Bishanpore in Imphal.

After the demise of 8th Guru Harkishanji, Guru Teg Bahadur Sahibji was installed as 9th Guru at Baba BAkala village in Amritsar District on 16th April 1664 AD. He stayed for some time at Bakala by imparting instructions relating to Guru Nanak mission.

He then visited Harmandir Sahib at Amritsar and had a holy dip in the sacred Sarover constructed by Sri Guru Ram Dassji. After leaving Amritsar he halted at several place and communicated spiritual discourses generating devotions to one God.

On crossing river Beas he reached village Hazara near Kartarpur where the devotees constructed Gurudwara in commemoration of his visit. The Guru proceeded further in stages and reached Kiratpur, where he did not like to stay for not offending his rival group present there.

Thus rested on some land six mile away, which he subsequently purchased from Raja Kahlur and founded city Annandpur in 1665 AD. In order to spread the names of the true God, Guru Teg Bahadurji started his missionary tour in December 1665 AD from Anandpur and first halt was at Molowat in Patiala state and blessed the people with God's name.

As the water of the area was not good to drink, Guru asked to repeat the name of God over the wall nearby draw water there from and the water was found to be pure and sweet. His Guru continued his journey, visited many places of which prominent are Kurukshetra, Agra, Prayag, Banaras (where shoe & coat of Guruji are still preserved). At Gaya Guru exposed the hypocrisy and deceit of the Brahmins, exhorted them to meditate on God and thoughts his Sikhs to remain ever free from their toils.

The Guru continued his missionary journey arrived at Patna. Hearing the fame of Gurujee, people of all walks of life rushed to him for Darshana, made offerings and constructed a magnificent mansion, presently converted into Harimandir. While morning prayers was being enchanted as per daily routine, an envoy from Raja Ram Singh, son of Mirja Singh of Ambar (Jaipur) arrived and later made offerings to Gurujee.

The envoy narrated the object "The Emperor Aurangzeb" has ordered my master to invade Kamrup (Assam) kindly extend your protections as the areas are full of Jadu-Mantar. Black magic which plays disastrous role for human beings. My master will soon arrive in person to offer homage at your lotus feet and to solicit your mercy. The Guru then advice to continuously meditate on "God's name" and god will so good. I am already on missionary tour and will reach Assam in stages via Malda, Dacca etc.

On hearing that his rayed has been accepted Raja Ram Singh, Commander of Emperor Aurangzeb's army felt inspired that at the mercy of Sri Teg Bahdur his victory is sure and stared preparing to march ahead on expedition to Assam, The Guru then stationed his mother and wife at Patna entrusting them to his brother in-law Kirpal Chand and set out this missionary journey to eastern region.

Wherever he went he was received with great honor and the people to whom he enjoined devotion to one God and communicated religious instructions. He thought Mangher, Bhagalpur, Rajmahal, Malda, reaches Dacca in stages.

Massand named Bulaki Das resided at Dacca, whose mother had taken a vow that if the Guru ever visited the place, she would request him to sit on the couch which was made for Guru, dressed him with the cloths which she had spun herself and serve him a dainty meal prepared by her own hands. The Guru knowing her devotion and desire of heart went without any other guidance, straight to her residence and called to her from outside on hearing the Guru she ran forth full of joy and placed her head on the feet of Guru.

There are three historical Gurudawaras Known As:

1. Guru Nanak's Temple at Sujatpur in which there is a well and it bears Gurumukhi inscriptions proving its antiquity.
2. Sakher Mandir near Rayer Bazar when Guru came to know that water of this place was not good for people to drink he asked the people to repeat the name of god and draw water. It was surprising that to all the water of the well become potable and started changing its colour.
3. Sangat Tola Gurdwara where Guru Teg Bahadur Ji stayed while at Dacca and blessed Raja Ram Singh during expedition to Assam, assured all protection against evil effects of black magic and jadu mantar etc.
   
   Raja Ram Singh therefore proceeded to Rangamati area, the Mughal's outpost and camped his army there. On hearing the arrival of Guruji the inhabitant of Dacca rushed to honor him and received his spiritual instructions and benedictions. The Guru seeing their enthusiasm said that Dacca is the store house of faith on Guru Nanak Mission.
   
   The Guru then set out for Assam and after crossing the River Brahmaputra reached Dam Dama Sahib (visiting place of Guru Nanak) on the banks of the river Brahmaputra, which was named as Dhubri by him.
   
   When Raja Chakradhar of Kamrup heard of Raja Ram Singh's arrival to attack him he vowed to destroy him and his army and ordered all the women who were famous for their magical skill and one such woman was Netai Dhuban by name.
   
   On the other side Sri Guru Teg Bahadurji alerted Raja Ram Singh to shift his army, camped alongside river bank to higher place, as a created flood is likely to effect at night. Thus the flood created at night with the power of black art had washed away those who did not shift to higher places and those who had shifted were saved.
   
   By seeing the poser of black magic the soldiers in the camp of Raja Ram Singh were extremely demoralized but the Guru assured them that nothing would happen to them. They should concentrate on almighty and repeat the name of God. When the magical attempt could not harm in the presence of Guru Teg Bahadur, she (Netai) became furious and hurled a big stone (several meters long) at Guruji but due to the spiritual powers of Guruji, the stone fell aside with such an impact that more than half of it was penetrated into the ground.
   
   Failing in her attempt she uprooted a "Pipal Tree" and riding on it, made another attack on Guru. The "Pipal Tree" stopped in the air before it reached him. When Netai felt powerless grew weary of her efforts, she was convinced about the divine power of Guru Teg Bahadur and begged to be pardoned she fell on her knees, openly accepted her defeat and prayed that her name should remain and people should remember her name. The Guru told her that this place will become big town and will be known as Dhubri on your name provided you do not indulged in such black art in future.
   
   One night Kamrup Raja's mother saw in a vision the Goodness Devi saying, "Guru Nanak has taken birth in the Kaliyuga, on his religious Gaddi Sri Guru Teg Bahadur is reincarnated, he is here with Raja Ram Singh who has become his discipline. Nowadays the Guru is Sovereign and no one his strong enough to oppose him go and bow down to his lotus feet, your rule shall be everlasting."
   
   Thus the Kamrup Raja approached Guruji and made humble prayer not to allow him to fall in to the power of Mughal Empire. The Guru advised him not to worry anymore and assured that God will take care of him. On this Raja was delighted and request the Guru to set his foot on his city with Raja Ram Singh. Thus with the influence of Guru, peaceful negotiations were reached and both the Rajas became friends, "Gurubhai" and exchanged turbuns for lifelong amity.
   
   From both side offerings were made to Guruji due to the peaceful negotiation, bloodshed was avoided. On the advise of Guruji, soldiers of both the Rajas built the mound of earth and cover the root of the Piple Tree which was hanging in the air. Each soldier brought five shieldful of earth from Ranga Mati Hill. The Guru then got constructed a shrine at the top of the mound which could be seen from great distance, in the name of Guru Nanak.
   
   Some of follower of Guru remained behind in Dhubri, to look after the temple (Holy Shrine) and their decedents are ever found in Goalpara and other place of Assam. Sri Guru Teg Bahadur spent some more days at Dhubri Saheb Gurdwara. The devotees on hearing of his fame started pouring in crowds after covering long distances for his darshan and obtain his blessings.
   
   He was given great honor throughout the country and his reputation having reached Raja Ram Singh (Ram Manikya) of Tripura and Jaintia of Assam who had no offspring and earnestly desired a son, he with his two wives came and made obeisance to the Guru and while making his request he felt abashed. The Guru knowing the state of his mind encouraged him to speak and then the Raja requested for the boon of an heir to his throne. In reply the Guru took off his signet ring, stamped on Raja's thighs and said that the impression of my seal shall be on the forehead of your son and name him as Ratan Rao, by this you should know that Guru Nanak has mercifully granted the off springs and therefore make him a Sikh.
   
   The Raja also had the Charan Pahal and became a Sikh. After the death of Raja Ram Manikya, his son Ratan Rao ascended the throne of Tripura as Ratana Manikya and came to Anandpore Saheb to pay his respect to Guru Gobind Singh the son of Sri Guru Teg Bahadur, with Price less presents.
   
   The Emperor Aurungzeb had brutally resorted to the process of converting the Hindus into Islam. The high caste Hindus approached Guru Teg Bahdur at Anandpur and told the sad story as too how the Hindus were being converted, not withstanding to the six months respite granted to them.
   
   "We have come to seek your protections in whatever way deemed most expedient," they said The tale of woe and suffering narrated by pundits, plunged the Guru in deep thought. It was clear that the Aurangzeb had almost lost his soul and started the path of sheer brutality. The death and sufferings of countless ordinary persons was not producing any effect on the hardened conscience of Aurangzeb and subordinate rulers.
   
   Then Guru Teg Bahadur said that a holiest, purest person and most revered by the people has to lay down his life in an attempt to rouse the sleeping soul of the Emperor. Such a sacrifice would also generate courage in the mind of oppressed and would learn to live with the honour or die rather than accepting conversions.
   
   Balak Gobind Singh who was of 9 years age heard the conversation and replied "why to search a holy and purest person, who can be holier and pure than you?" So, Guru Teg Bahadur resolved to go to Delhi and thus sacrificed himself for the sake of Hindu religion in 1675 AD. This way the further conversions were plugged as the mind and soul of the Emperor Aurangzeb was shaken. His own conscience started humiliating for this heinous act of killing of a man of God.
