" Your teachers
Are all around you.
All that you perceive,
All that you experience,
All that is given to you
or taken from you,
All that you love or hate,
need or fear
Will teach you--
If you will learn.
God is your first
and your last teacher.
God is your harshest teacher:
subtle,
demanding.
Learn or die. "

― Octavia E. Butler , Parable of the Sower (Earthseed, #1)
