Graduation. What does it mean?

Graduation.
What does it mean?
When a person graduates they receive a diploma.
As the students received their diplomas they are instructed to accept the diploma with their left hand and shake hands with their right.
This was to insure the procession went smoothly.
Though I believe there’s more to this than just moving along in a consistently steady manner.
They accept the diploma with their left hand that they may be left with the knowledge and confidence to advance and to improve their lives and the lives of others.
They shake the right hand of their mentors that they may strive to always do the right things for themselves and others.
Doing these things means you have truly graduated.
