Vaheguru ji ka khalsa, Vaheguru ji ki fateh Sangat ji,
I have a question regarding vaar on ang 947. The first pauri of vaar has rahao tuk
"ਵਾਹੁ ਵਾਹੁ ਸਚੇ ਪਾਤਿਸਾਹ ਤੂ ਸਚੀ ਨਾਈ ॥੧॥ ਰਹਾਉ ॥"
The gursikh giving santhaya at our gurudwara said that this tuk should be ucharan at end of all pauri's after the last line cos all the following pauri have last line not rhyming with rest of shabad in pauri and this rahao tuk rhymes and as per him it is Guru Hargobind Sahib ji who told the sikhs to read this tuk at end of each pauri in this vaar.
Is this what the sangat does too, this gursikh has done santhaya from taksal (not to create debate on jatha or taksal issue) but I want to know if Bhai Randheer Singh Jee has said something about this vaar. Thank you jee
