Perhaps the only real teacher is the person themselves and perhaps it is only when the person themselves allows themselves to teach themselves that the person truly learns and then both teacher and student appear simultaneously?
I am at the same time both teacher and student mostly teaching myself or at least learning how to learn which may be the most important lesson of all in which case I may be my own best teacher because if I pay close enough attention to myself then I can see my own pitfalls as well as my strengths as long as I ALSO notice the times when my ego is involved and I then transcend my own ignorance and barriers to learning.
After a while you learn the subtle difference between holding a hand and chaining a soul and you learn that love doesn't mean security and you begin to learn that kisses aren't contracts and presents aren't promises
you begin to accept your defeats with your head up and your eyes open, with the grace of a woman, not the grief of a child and you learn to build your roads on today because tomorrow's ground is too uncertain and futures have a way of falling down in mid-flight
after a while you learn that even sunshine burns if you get too much so, you plant your own garden and decorate your own soul instead of waiting for someone else to bring you flowers and you learn you really can endure that you really are strong you really do have worth and you learn and you learn with every good-bye you learn.
Youth is a beautiful dream, on whose brightness books shed a blinding dust. Will ever the day come when the wise link the joy of knowledge to youth's dream? Will ever the day come when Nature becomes the teacher of man, humanity his book and life his school? Youth's joyous purpose cannot be fulfilled until that day comes. Too slow is our march toward spiritual elevation, because we make so little use of youth's ardor.
