Nelson Mandela, writing from his prison cell

“You may find that the cell is an ideal place to learn to know yourself, to search realistically and regularly the processes of your own mind and feelings. In judging our progress as individuals we tend to concentrate on external factors such as one’s social position, influence and popularity, wealth and standard of education …. but internal factors may be even more crucial in assessing one’s development as a human being: honesty, sincerity, simplicity, humility, purity, generosity, absence of vanity, readiness to serve your fellow men – qualities within the reach of every soul – are the foundation of one’s spiritual life …. at least, if for nothing else, the cell gives you the opportunity to look daily into your entire conduct to overcome the bad and develop whatever is good in you. Regular meditation, say of about 15 minutes a day before you turn in, can be fruitful in this regard. You may find it difficult at first to pinpoint the negative factors in your life, but the tenth attempt may reap rich rewards. Never forget that a saint is a sinner that keeps on trying.”
