Upasika Kee was a uniquely powerful spiritual teacher. Evocative of the great Ajahn Chah, her teachings are earthly, refreshingly direct, and hard hitting. In the twentieth century, she grew to become one of the most famous teachers in Thailand—male or female—all the more remarkable because, rarer still, she was not a monastic but a layperson. Her relentless honesty, along with her encouraging voice, lead many contemporary Buddhist teachers to recall Upasika Kee fondly and often. Pure and Simple, the first widely available collection of her writings, will be gratefully received not only by those who know Upasika Kee, but by anyone who encounters her here for the first time.
