Mentor, a word originated from Odyssey by Homer
The mentor and mentee relationship is not one-way traffic. As much as the mentee learns from the Master, the Master himself grows and benefits from that relationship.
As the Great Soul or “Mahatma” Gandhi aka Mohandas Karamchand Gandhi ex Porbandar, Gujarat, British India famously said-
“At the time of writing, I never think of what I have said before. My aim is not to be consistent with my previous statements on a given question, but to be consistent with truth as it may present itself to me at a given moment. The result has been I have grown from truth to truth…” Mahatma Gandhi.
