Literally "teacher." One of the most important words in Sikhism, it has a number of related meanings. It can refer, depending on context of usage, to one of the ten Sikh prophets, the Sikh scripture, the Sikh community (Guru Panth), or God. The Sikhs had ten living Gurus, and the 10th Guru transferred the Guruship to the holy scripture, Guru Granth Sahib.
