The word Sikh means a disciple. A Sikh is a person who believes in One God and the teachings of the Ten Gurus, enshrined in the Guru Granth Sahib, the Sikh Holy Book. Additionally, he or she must take Amrit, the Sikh Baptism. Sikhism is a practical religion–a faith of hope and optimism. Its ideals form a large part of the more progressive elements in humanity today.
