The Damdami Taksal is a traveling Sikh university, founded by the tenth Guru of the Sikhs, Guru Gobind Singh Ji. The tenth Guru, Guru Gobind Singh was at Anandpur Sahib delivering his Sikhs to Sachkhand. A Gursikh was reciting his daily prayer from Guru Granth Sahib with love and respect, when he made a mistake. The Guru corrected his mistake, informing him that prayer from the Guru Granth Sahib is just like a limb of Guru, and making a mistake while reciting Gurbani is like hurting Guru.
Following this Daya Singh, along with other respected Gursikhs asked Guru if they could follow him, learning proper pronunciation and prayer from the Guru Granth Sahib. "Oh keeper of the poor! Bless us with the understanding of Gurbani. Without an understanding we don't know whether what we do is correct or incorrect."
