In a looser sense, a figure from the past or present can serve as an ideal, someone to model yourself after. Through much research and some imagination on your part, you turn them into a living presence. You ask yourself—what would they do in this situation or that? Countless generals have used Napoleon Bonaparte for just such a purpose.
In Spanish they say al maestro cuchillada—to the Master goes the knife. It is a fencing expression, referring to the moment when the young and agile pupil becomes skillful enough to cut his Master. But this also refers to the fate of most mentors who inevitably experience the rebellion of their protégés, like the cut from a sword.
One repays a teacher badly if one remains only a pupil. —FRIEDRICH NIETZSCHE
