A few facts, figures and basic tenets of Sikhism: It is the fifth-largest religion in the world with 25 million followers, behind only Christianity, Islam, Buddhism and Hinduism. It was founded in India more than 500 years ago by prophets known as the Sikh Gurus, who preached a new message to improve life on Earth and enable human beings to come closer to God. The place of worship and learning is known as a gurdwara or temple, open to visitors of any faith in need of shelter, comfort or food. Because the Sikh faith does not have an ordained clergy, any woman or man from the congregation may lead religious services. Sikhs display the commitment to their religion by wearing five articles of faith: kes (uncut hair); kanga (small comb); kachera (shorts worn as an undergarment); kirpan (sword worn with a shoulder strap); kara (bracelet). The Sikh holy book, the Guru Granth Sahib, is a collection of revelations that offers direction on an ethical life and poetic compositions of the Sikh Gurus, as well as writings of non-Sikhs, all sung as hymns. Sikhs are guided by three daily principles: work hard and honestly; share your bounty with the less fortunate; remember God in everything you do.
