Founded by the Guru Nanak (born 1469), Sikhism believes in a non-anthropomorphic, supreme, eternal, creator God; centering one’s devotion to God is seen as a means of escaping the cycle of rebirth. Sikhs follow the teachings of Nanak and nine subsequent gurus. Their scripture, the Guru Granth Sahib – also known as the Adi Granth – is considered the living Guru, or Sikh faith and theology’s final authority. Sikhism emphasizes equality of humankind and disavows caste, class, or gender discrimination.
