I'm a believer of The Guru Granth Sahib and have quoted everything from that, the quote you give is not from that, it's something I'm not familar with (have heard of them, but not read them) and have no knowledge of it at all. So pardon my ignorance and explain this quote further to me...are you asking someone who is a Sikh to get 'killed' at the hands of other Sikhs, or have I got it wrong ?
