Hmmmm..........a disturbing video, whilst Gurbani is being recited in any form we are supposed to cover our heads as a mark of respect. The Dastaar is the crown of the Sikh, he is doing beadbi of his Dastaar, Kesh and Guru Granth Sahib Ji Maharaj.
His cult however feel that this "reaction" is very spiritual?!?!?!?!?! Then again they believe there is a human man as the current Guru of the Sikhs?!?!?!?!?!
Sorry if I appear to be side tracking.
Naturally it cant be helped if you really feel the power of Bani, however please keep in mind that there is certain conventions that we follow in the presence of Antarjami Dhan Dhan Sri Guru Granth Sahib Ji Maharaj.
Waheguru Ji Ka Khalsa Waheguru Ji Ki Fateh!
