In order to ensure proper body discipline the following five external adaptations on the body of a Sikh are a must:
(1) KACHH (ਕੱਛ) – a specially designed underwear
(2) KARRA (ਕੜਾ) – wrought iron bangle to be worn on the right forearm
(3) KIRPAN (ਕਿਰਪਾਨ) – iron sword to be slung across the body with a strap from the right shoulder
(4) KANGHA (ਕੰਘਾ) – wooden comb to be kept along top-knot of hair onhead
(5) KESKI (ਕੇਸਕੀ) – a turban of convenient length for respectful protection of hair
The above five external adaptations constitute an external form of a Sikh. This form must be kept up at all time, otherwise indiscipline would creep-in in the wake of any slackness on this score.
