In order to make it easier for his followers to recognize each other, Guru Gobind Singh Ji, choose five marks which symbolize the Sikhs. The five signs are :

1.	Kesh	-	Uncut hair. Historically, unshorn hair was a sign of spirituality and sainthood; this is consistent with the concept of saint-soldier in Sikhism. Also, keeping one's hair intact indicates resignation to the Will of God.
2.	Kangha	-	A small wooden comb used to keep the hair tidy at all times. Typically worn underneath a turban, this represents cleanliness; and as such, is a practical way to look neat and pure at all times.
3.	Kach	-	Long undershorts typically worn by soldiers to ensure freedom of movement.
4.	Kara	-	A steel bracelet worn around the wrist as a reminder of one's faith.
5.	Kirpan	-	A saber to be used as a last measure of protection in case the need to defend oneself, or another, arises.
