Because the word “guru” means teacher, it is often used to refer to teachers of all kinds—be they teachers of music, ayurvedic medicine, cooking, etc. The title “Jagad Guru” is normally used to refer to yoga masters who have disciples all around the world from different places, nationalities, faiths, etc. However, in the deepest sense, “Jagad Guru” means a yoga master whose teachings are relevant to and can be applied in the personal lives of every person—regardless of their ethnicity, nationality, or sect. (“Guru” means servant; “guru” does not mean master. “Jagad Guru” refers to a person who sees himself as a servant of all mankind, not a particular race, religion, or nation.)
