Over twenty million Sikhs follow a revealed, distinct, and unique religion born five  centuries ago in the Punjab region of northern India. Between 1469 and 1708, ten  Gurus preached a simple message of truth, devotion to God, and universal equality. Often mistaken as a combination of Hinduism and Islam, the Sikh  religion can be characterized as a completely independent faith:

Sikhism  rejects idolatry, the caste system, ritualism, and asceticism. It recognizes the  equality between both genders and all religions, prohibits the intake of any  intoxicants, and encourages an honest, truthful living. Sikhs have their own holy scripture, Guru Granth Sahib. Written, composed, and compiled by the Sikh Gurus themselves, the Guru Granth Sahib serves as the ultimate source of spiritual guidance for Sikhs. While the Sikhs hold their Gurus in high reverence, they are not to be worshipped; Sikhs may only worship God.

Members  of the Sikh community are mainly concentrated in their homeland, Punjab;  however, substantial Sikh populations exist throughout the rest of India and the  world. Punjabi, a variant of the Hindi language with some Persian influence, is  the spoken and written language of the Sikh people. Male members of the Sikh religion use the name, Singh (lion), as their middle or last name, while females use the name, Kaur (princess). Sikhs tend to be industrious and pioneering; this  accounts for their general success wherever they live and settle. The  hard-working nature of the Sikhs is derived from their religion, which can be best characterized as a faith of unlimited optimism.
