Mug "Ideal Teachers" Nikos Kazantzakis Quote in Greek

A perfect teacher gift: a quote attributed to Nikos Kazantzakis on the ideal teacher, who use themselves as a bridge for their students to cross over; in the original Greek. It includes a vector of his signature. The English translation is on the other side of the mug: "Ideal teachers are those 
who use themselves as bridges 
over which they invite 
their students to cross; 
then, having facilitated their crossing, 
joyfully collapse, encouraging them 
to create their own".
