Guru Gobind Singh Ji

Gobind (Center point of universe) Rai name was given to you by Guru Tegh Bahadur Sahib when he were in Dhaka. When you started to create army, You though your army should be looked like son of Akalpurak that's why you introduce five K's to sikh, Kes(hair), You wanted that all sikh should look like lion and should be sabat surat (Should be remain same from birth), Hair also keep us away from illness. Second K is for Kanga(Comb) to keep hair clean and to remove tangles as hair are God gift. Sikh keep it under turban. Third K is for Kachh (Soldiers Shorts), It was difficult to fight with loose dhoti and it is for reminder that to keep relationship with own husband/wife. Fourth K is for kirpan which comes from "Kirpa and Aan" Kirpa means kindness and Aan means self-respect and self-defence. Fifth K is for kara means Satguru ki Hathkadi which is made of Iron which is unbreakable bond with Akalpurak (God), It is also to tells sikh that God having not beginning or end.
