Hi From Wikipedia : A guru (Sanskrit: गुरु) is one who is regarded as having great knowledge, wisdom and authority in a certain area, and who uses it to guide others (teacher). In sanskrit gu means darkness & ru means light. As a principle for the development of consciousness it leads the creation from unreality to reality, from the darkness of ignorance to the light of knowledge. In its purest form this principle manifests on earth as a divine incarnation (saint), a person with supreme knowledge about God and all creation. Other forms of manifestation of this principle also include parents, school teachers, non-human objects (books) and even one's own intellectual discipline.
