Guru
"Guru" is a title. It can mean two different things. Ideally these things go together.
- A spiritual teacher or leader.
- A being who has become completely enlightened, and is now god incarnate - all traces of personality, individual self interest, and limited consciousness stripped away, leaving manifest, immanent divinity.
Type 2 gurus are rarer than hen's teeth.
http://ammachi.org/ is likely to be one.
