When Guru Gobind Singh established the Khalsa in 1699, he asked all Sikhs to wear five symbols expressing their allegiance to the new Sikh community. These five symbols are known as the five Ks.
Kesh is uncut hair on the head and body, symbolizing acceptance of God's will. This gave rise to the distinctive Sikh turban, a way to keep the long hair clean and tidy.
Kachh is a pair of white cotton shorts worn as an undergarment. It is practical in battle, and therefore symbolizes moral strength and chastity.
Kara is a steel bracelet symbolizing responsibility and allegiance to God.
Kangha is a wodden comb that represents personal care and cleanliness.
Kirpan is a steel dagger, a symbol of resistance against evil and defense of truth.
