Chaur Sahib is an implement normally found next to the Manji sahib where the Sri Guru Granth is pla sahib is placed during the day within the Gurdwara's darbar sahib(Main Hall). The Chaur is used to fan the Granth as a sign of reverence and respect for the scriptures. These days, the chaur is usually constructed from yak hair mounted in a wooden or metal handle. The sevadaar (volunteer) respectfully waves the Chaur Sahib above the Guru Sahib as a sign of respect and dedication. (from sikhiwikhi) The questions are- -Why have the chaur sahib when we have electric fans that can provide a healthy flow of air and keep any flies away ? -Is this not a ritual that is just pure outwardly behavior ? -If it is not a ritual, then what is it ? It would be interesting to see the different views and discussions on this since I have found lately that phrases or words like; vedic or blind practices keep getting thrown about to try and define gurmat, as if trying to enclose gurmat in a box. But I sense that sometimes, we don't actually understand the differences between different aspects of approach to Waheguru.
