those who are Sikh have no past, they have no future, they can only breathe in the present, Sikh warrior was and is our brother, even if he was not a Sikh. and being born into a Sikh family means nothing. for example our SRO guru Nanak Dev Jo was born into a Hindu family, but he was always a Sikh.

i recommend you bow down to SRO guru granth sahib ji, and repeat "I am your sikh, please show me your path" and officially become a sikh.
