Learning and Teaching

I am reading The Pilgrimage by Paulo Coelho.
It is different from The Zahir or Alchemist, in the sense that it has more of Christian esoteric concepts and spiritual symbols.

On page 163 of the edition I read, in chapter titled "Personal Vices", I noticed a very interesting-true assessment:

Teaching is only demonstrating that it is possible. Learning is making it possible for yourself.
