…the inner reality of man is a demarcation line between the
shadow and the light, a place where the two seas meet; [1] it is the lowest point
on the arc of descent, and therefore is it capable of gaining all the grades
above. With education it can achieve all excellence; devoid of education it
will stay on, at the lowest point of imperfection.
- ‘Abdu’l-Baha (‘Selections
from the Writings of 'Abdu'l-Bahá’)
[1] Qur'án 25:55, 35:13, 55:19-25
