Sikhism originated in the 15th century in the Punjab region of South Asia. It was founded by Guru Nanak and is based on teachings of equality, justice, and service. Sikhs follow 10 gurus and spiritual guidance from the Guru Granth Sahib scripture. Practices include maintaining uncut hair, wearing the five Ks, and serving in the free community kitchen. Sikhism preaches equality for all people regardless of gender, race, or religion.
