Aung San Suu Kyi recently visited Oslo to finally give her Nobel Peace Prize speech. She is often compared to other Peace Prize laureates, in particular Nelson Mandela and the Dalai Lama. One of the things all of them share is a strong commitment to meditation.
I have always thought of Nelson Mandela as a person with some meditative qualities. Reading his recently published Conversations with Myself seems to confirm not only these qualities, but also meditation as part of his practice, though his meditations are thematic rather than technical.
