Wisdom is not a matter of mere talking; it is difficult
to express it. Having cart-loads of knowledge and books
is in vain, as these enhance one’s ego. The literate and
illiterate are not the fundamentals of morality because
an educated person can be an evil-doer, whereas the
uneducated may be good in actions. In the spiritual
domain of life, the criterion of judgement lies not in
education but in one’s deeds.
(Guru Nanak)
