I'm no expert but heres my view , obviously cleanliness is important , but the our aim is to clean our inside by doing path with love . So our mind does not wander , focus on the Lord at all times. Dr Vir singh in his book Guru Nanak Chamatkar , mentions Sri Guru Nank Dev Ji , did his worldy chores and recitation of the Lords name side by side. So we should aim to do this , and key focus on love for the Lord. It mentioned as we have love for our children , our wife /husband , like the magnet attracts to iron , Guru Nanak Dev Ji Maharaj had much much more love for the Lord. Based on this our aim should be recite Gurbani so it hits our heart and love for the Lord is ignited.
So based on this , and your spiritual level you would automatically react accordingly based on how you see Gurbani , the shabad.
Whose heard the story of baba sri chand laughing and asking Guru Ram Das ji why his beard is so long and Guru Ram Das ji said to wipe the feet of saints like you and Guru ji bent over and started cleaning Sri chands feet. Iv heard different versions of this story. Some people deny it
Didnt sri chand reject Guru Nanak Dev jis dharam and start his own sect. He had a lot of yogic powers.
I thought if we have love for our guru like a child would with a father then having to shower again wouldn’t have to be a requirement especially if you’ve cleaned yourself and changed clothes and everything? Isn’t just one ishnaan necessary to sit and do paath next to your guru?
