It is from these comrades in the struggle that I learned the meaning of courage. Time and again, I have seen men and women risk and give their lives for an idea. I have seen men stand up to attacks and torture without breaking, showing a strength and resilience that defies the imagination. I learned that courage was not the absence of fear, but the triumph over it. The brave man is not he who does not feel afraid, but he who conquers that fear.

Explanation:

 

It was from these comrades in arms that Mandela had discovered the meaning of bravery. He claims that he had seen men and women lose their lives for an idea on several occasions. He had witnessed men withstand attacks and torture without cracking, demonstrating a tenacity and resilience that was beyond belief. He discovered that courage was the triumph over fear, not the absence of fear. A brave person is not one who is fearless, but one who overcomes fear.
