The Sikh Code of Conduct is known as the Sikh Rehat Maryada. It is based upon the teachings of Guru Granth Sahib and Sikh traditions and conventions. These rules are meant for carrying out religious ceremonies and enforcing the discipline of the faith in a uniform manner throughout the world.
No individual or organisation, whosoever important as it may be, has a right to either amend these rules or to frame new ones. This power rests with the Panth (the whole community) acting through their Panj Pyare (five beloved ones). Any rule which overrides the basic teachings of the Faith is ignored.
All intoxicants such as alcohol and tobacco, trimming hair (keshas), and eating meat are forbidden. Adultery and pre-marital relations are considered a sin. A Sikh should regard another man’s wife as his sister or mother and another man’s daughter as his own daughter. The same rule is applicable to women as well.
