The chief ceremony initiated by Guru Govind Singh was the Khanda ka Pahul or baptism by the sword.
He also was a Khatri, and was chosen by Guru Nanak in preference to his own sons.
The religious creed of Guru Govind Singh was the same as that of Guru Nanak: the God, the guru and the Granth remained unchanged.
It was Guru Arjan who compiled the Granth or Sikh Bible, out of his own and his predecessors' compositions.
The fighting spirit of the people of for iveness and endurance, upheld Guru Nanak's g p was roused and satisfied by the spiritual and military leader.
Little is known of the ministry of Angad except that he committed to writing much of what he had heard about Guru Nanak as well as some devotional observations of his own, which were afterwards incorporated in the Granth.
Both obey the general injunctions of the Sikh gurus, but the Sahijdhari Sikhs have not accepted the pahul or baptism of Guru Govind Singh, and do not wear the distinguishing habiliments of the Kesadhari, who are the baptized Sikhs, also called Singhs or lions.
The death of the emperor Aurangzeb brought a temporary lull: the guru assisted Aurangzeb's successor, Bahadur Shah, and was himself not long after assassinated at Nander in the Deccan.
In the Autobiography of Jahangir it is stated that the guru was imprisoned in the fortress of Gwalior, with a view to the realization of the fine imposed on his father Guru Arjan, but the Sikhs believe that the guru became a voluntary inmate of the fortress with the object of obtaining seclusion there to pray for the emperor who had been advised to that effect by his Hindu astrologers.
But while Nanak had substituted holiness of life for vain ceremonial, Guru Govind Singh demanded in addition brave deeds and zealous devotion to the Sikh cause as proof of faith; and while he retained his predecessors' attitude towards the Hindu gods and worship he preached undying hatred to the persecutors of his religion.
