8For centuries, Dzogchen - a special meditative practice to achieve spontaneous enlightenment - has been misinterpreted by both critics and malinformed meditators as being purely mystical and anti-rational. In the grand spirit of Buddhist debate, 19th century Buddhist philosopher Mipham wrote Beacon of Certainty, a compelling defense of Dzogchen philosophy that employs the very logic it was criticized as lacking. Through lucid and accessible textural translation and penetrating analysis, Pettit presents Mipham as one of Tibet's greatest thinkers.
