Some people may think that okay, when we say Perfect Master,we're talking about God, or we're talking about prophet, or we're talking about something like that. But really, in laymen's term, to explain it, is that if somebody is a flight instructor, you would call them a flight instructor, or a flight teacher, or one who teaches about airplanes. If one was a professor of maths, he had mastered it, then you would call him teacher in maths, or instructor in maths [. . .] the definition of a Perfect Master is the one who can give us the perfectness, one who can teach us the perfectness.
