I mentioned the number 84 becaus ethere are 84 stairs there at Bauli shaib. People sit in one Pauri do one Japuji shaib Paath , then do ishnaan and aagain sit on second pauri and repeat same untill all 84 pauris get completed. If you You go there you will see every day 10-20 people doing that. ALl the history regarding 84 japuji sahib Paath and going through 3 times , and Ura arra at damdma sahib , is written on the board at each Gurudwara Shaib with clear mentioning of Gurbani Tuk or any other reference.
