Amritdhari: those Sikhs who have been initiated with amrit ceremony. It is mandatory for them to wear the Five-Ks: Kes (uncut hair), Kangha (comb), Kirpan (sword), Kachha (knee-length pants) and Kara (steel bracelet on the right wrist). They also follow the Khalsa code of discipline such as strict dietary rules such as vegetarianism, saying daily prayers. Kesdhari: those Sikhs who have not been initiated, may or may not ever get initiated. They keep their hair uncut, wear turban, and generally observe some or all elements of the Khalsa code of discipline. However, they do not follow one of more practices of the Amritdhari, and may observe some codes or practices occasionally.
