A person whose job is to teach people a practical skill

Other teachers may provide instruction in craftsmanship or vocational training, the Arts, religion or spirituality, civics, community roles, or life skills.Informal learning may be assisted by a teacher occupying a transient or ongoing role, such as a parent or sibling or within a family, or by anyone with knowledge or skills in the wider community setting...
A trusted friend, counselor or teacher, usually a more experienced person.

A guru is one who is regarded as having great knowledge, wisdom and authority in a certain area, and who uses it to guide others. 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. Other forms of manifestation of this principle also include parents, school teachers ,books and even one's own intellectual discipline. Many Gurus ask for

I see.
