Sadhu Sundar Signh (1889-1929) was born into a Sikh family. After his mother died he planned to kill himself if God did not reveal himself. To his surprise, Jesus appeared to him and Sadhu was immediately converted. He was rejected and cast out of his family, and began walking to villages telling them about Jesus. He had many visions, making him one of history's greatest mystics. This book brings together many of Sadhu's teachings and information about Sadhu, to give the reader a good picture of Sadhu's teachings, and the man himself. This book was first published in 1921. Sadhu traveled to Tibet for the final time in 1929, never to be seen again. Sadhu's teachings were collected from scattered sayings on the same topics, to make a complete theology in picture form, showing his way of life and his mystic experience: an organic whole. But the authors of this book also interviewed Sadhu in person to receive some of this information. And if this book has any merit beyond fidelity to fact, it largely consists in the attempt to seize and bring out this inner unity and coherence.
