I always tell students on Opening Day to resist the Guru model of wisdom. Philosophy is collaborative. Authority figures do not appeal.
"...there is no teacher, no pupil; there is no leader; there is no guru; there is no Master, no Saviour. You yourself are the teacher and the pupil; you are the Master; you are the guru; you are the leader; you are everything." Well, Krishnamurti, I wouldn't go that far.
