In Spanish they say al maestro cuchillada – to the Master goes the knife.
It’s a fencing term where the student finally is able to cut his Master.
We are all students of something or other and it’s human instinct to rebel against our superiors or mentors. This happens particularly when our own intuition and insights start to loom over our Masters.
It’s a natural process and yes, even our mentors used this method to get to where they now are.
