But the power of knowledge is still greater. He is, however, a thinking animal. Knowledge directs his actions and enables him to find the difference between right and wrong, good and bad. It helps him overcome his weakness and faults and face dangers and difficulties with courage and confidence. It gives him mental, moral and spiritual advancement. Besides this, it is through knowledge that man has gained mastery over nature.
