Their bani is in the Guru Granth Sahib ji Maharaj, in the form of the Svaiye, or 'Panegyrics of the Bhatt', or Bhattan de Svaiye.

Sakhi 75. Sarup Singh ji records that there were a number of skirmishes between the Khalsa and Raja Ajmer Chand, who would taunt the Sikhs. On 2nd December 1703 AD, he attacked Anandpur Sahib. Pitched battles took place. Guru ji commanded the bearer of the Khalsa Standard - Mann Singh ji - to go forwards, he struck the Khalsa Battle Standard into the ground. He fought valiantly. The Khalsa Battle Standard was hit and fell to the ground. This news was conveyed to Guru Gobind Singh ji Maharaj at Takht Sri Keshgarh Sahib. Guru ji undid his own turban, took out a section of his under-turban called keski, and raised it on top of his dastar as the Nishan Sahib. He said ' The Khalsa Nishan Sahib will never fall again'. Thereafter, blue Farlas were made by Bhai Uday Singh, Himmat Singh, Sahib Singh, Mohkam Singh and Alam Singh.
Sahibzada Baba Fateh Singh ji was six years old at the time, he looked in owe at his father's Farla. Guru ji smiled and said 'My son, this Farla will be eternally on this earth. It is the physical form and dress of Maha-Akal [The Great Timeless One], it should be respected the same as the Nishan Sahib.'
