I am now reading the autobiography of Nelson Mandela: "Long Walk to Freedom".   On page 77, he said: ....Part of my salary was spent on even more vital item - candles - for without them I could not study.  I could not afford a kerosene lamp; candles allowed me to read late into the night.  I was inevitably short more than a few pence each month.  Many days I walked the six miles to town in the morning and the six back in the evening in order to save bus fare.  I often went days without more than a few mouthful of food, and without a change of clothing. A friend, who was my height, once gave me an old suit of his and, assisted by considerable stitching and patching, I wore that suit every day for almost five years.  In the end, there were more patches that suit.

One marvels at this fantastic, incredible suffering that he has gone through.  I feel humbled and considerable admiration at how he is able to go through life with all the suffering, cruelty and injustice meted out to him.
Reading him is an inspiration.
