When Sundar Singh disappeared in the Himalayas in 1929, the world mourned. His 23-year pilgrimage as a sadhu had led him through at least 20 countries on four continents. He had profoundly influenced tens of thousands of people. Though hugely popular in India and Europe during his lifetime, Sundar Singh's writings have not been readily available to readers in the English-speaking world for decades. With "Wisdom of the Sadhu", a collection of anecdotes, sayings, parables, and meditations, his spirit has been brought alive for a new generation. Couched as they are in a distinctly Indian idiom, his teachings probe the essence of the Gospels with unusual freshness and offer insights of great value.
