Where does Chor Sahib Originate?

Question : Where does chor sahib originate from and why we do? 

Answer : This is to express our regards and our respect for the Holy Scripture, the True King. The king commanded the greatest power, hence also the maximum respect and honor, in the olden days. Guru Nanak Dev Sahib Jee said that the true kings are those who love God and help others to do that. They are the rulers of the hearts of the people. The political kings are temporary kings and their authority ends with their death. The Gurus are the true kings; they teach Truth and rule our hearts. The Guru Granth Sahib is the embodiment of the spirit of all the Sikh Gurus and many other holy men whose hymns are included in it. We respect them as the true kings. 

Also the King sat on a throne under a canopy. He used to have a fanlike structure to be waved over his head as a symbol of his royalty. The Guru Granth Sahib, being the true emperor, is provided all these regal paraphernalia in the Gurudwara. We install the scripture on a throne (called Manji Sahib) with pillows around for supporting it. A canopy (Chanani) is provided above the scripture in the same way as it was put over the head of a king while he attended his court. During the session (Diwan), a person, with Chaur Sahib in his/her hand, is always in attendance on the scripture installed respectfully in the hall. For maintaining due regards and respect, we carry this holy scripture to another room when the hall is to be cleaned or when the session is over for the day. Before we bring the Guru Granth Sahib in the hall, we set everything in the hall properly. This is the court of the Guru. You will understand the whole ceremony better if you bring into mind the scene of the courtroom where everything is set and made ready before a judge enters his court. The Guru Granth Sahib Jee is the Emperor of Emperors, hence all these ceremonial decorations.
