Guru Tegh Bahadur started to tour extensively to spread the teaching of Guru Nanak Dev Ji.  He visited important cities like Agra, Allahabad, Benaras, Gaya, Patna and Dacca, While the Guru was at Dacca; A messenger arrived from Patna to inform him of the birth of his son.  Guru Tegh Bahadur named his son Gobind Rai.

                Guru Tegh Gahadur returned to Patna, and was happy to see his wife (Mata Gujri) and his son Gobind Rai.  He found out that according to fresh orders from Aurangzeb, the Hindus were being suppressed and they were being forced to become Muslims.  Temples were being brought down and Mosques were erected in their places all over India.

                 Guru Tegh Bahadur left his family at Patna Sahib and returned to Punjab.  He went place to place to tell the people, that Aurangzeb wanted Islam to be the only Religion.  Aurangzeb had ordered his men to convert the infields (non-Muslims) to Islam, and if they refused to become Muslims, they were either killed or had to face starvation.

                 The Brahmins of Kashmir were the most oppressed for conversion to Islam.  They came to Guru Tegh Bahadur Ji to seek his help.  Guru Tegh Bahadur looked worried and the young son of his (Gobind Rai) asked him the cause of his worries.  Guru said to his son there is a need for a noble person to sacrifice himself in order to give heart to the Indians to resist oppression.  The big question was where to find such a noble person.  Young Gobind answered: Who could perform this task better than you could?  Guru Tegh Bahadur was very happy to hear this will get rid of all his anxiety.

                 The Entire assembly was strongly impressed by these words.  The disheartened Pundits saw a ray of  light and hope.  Guru Tegh Bahadur along with his four devotees (Bhai Mati Dass, Sati Dass, Dayal Dass and Gurditta) followed the Guru.

                 At Delhi Guru Tegh Bahadur and his companions were summoned to the council of chamber of the Red Fort (Diwan-I-Khas). They were imprisoned and tortured.  The Guru was asked why he was defending the Brahmins of Kashmir.  The Guru replied it was his moral duty to protect the innocents against cruelty and injustice.  The Guru was asked to embrace Islam, and offered many temptations for conversion. On Guru's emphatic refusal to abjure his faith, he was asked to perform miracle showing his spiritual power over death.  But the Guru Declined to accept both the options, and preferred death for the glory of faith. The death pronouncement against Guru Tegh Bahadur applied to his companions as well.  The infliction of the execution was proceeded, three days consecutively.

     Bhai Mati Dass was the first to be put on trial.  On his refusal to embrace Islam, the imprial Qazi (judge) decreed that Bhai Mati Dass be sawn like a log.  Therupon, Mati Dass was tied down between two logs and cut into twain, with a iron saw, by to executioners on Nov. 9, 1675 at Chandni Chowk, adjoining the Kotwali, Delhi, two days earlier prior the martyrdom of Guru Tegh Bahadur.  Bhai Mati Dass was a staunch devotee of Guru Tegh Bahadur.  He chose to embrace death than forsake his Guru and the humanitarian ideals of Sikhism.

     Next day, Nov. 10, 1675 was the turn of Bhai Dayal Dass.  The Qazi asked Bhai Dayal Dass to accept conversion to Islam.  On refusal, Bhai Dayal Dass was tied up like a round bundle and thrown into a huge cauldron of boiling oil.  He was roasted alive into a block of charcoal.  The same day Bhai Sati Dass was wrapped in cotton and set on fire when he declined to abjure his faith.  Bhai Dayal Dass and Bhai Mat Dass sacrificed themselves for the protection of their faith.  This is the tale of truth, how Bhai Mati Dass sacrificed his life and accepted death along with his companions for the sake of the mission of the Guru.

                             On November 11th 1675, the Guru was beheaded by the official executioner.  The Guru's head fell at some distance and was picked up by Bhai Jetha and taken to Anandpur.  At this moment a storm blew dust which helped Bhai Lakhi Shah cart the Guru's body to his house.  Fearing for his own life, he set his house on fire, containing the body of Guru Tegh Bahadur.

                 Guru Tegh Bahadur was a remarkable.  He composed his hymns in Hindi in 15 classical ragas and later on incorporated in the Adi Granth by his son.
