My childhood name was Iwajiro, and I was eight years old when I first entered at the gates of hell...One night in eighteenth-century Japan, at the hour of the Ox, a young boy named Iwajiro sits in a state of pure concentration. At the foot of Mount Fuji, behind screen walls and amidst curls of incense smoke Iwajiro chants the Tenjin Sutra, an act of devotion learned from his beloved mother. On the side of the same mountain, twenty years on, he will sit in perfect stillness as the summit erupts, spitting fire and molten rock onto the land around him. This is not the first time he has seen hell. This man will become Hakuin, one of the greatest teachers in the history of Zen. His quest for truth will call on him to defy his father, to face death, to find love and to lose it. He will ask, what is the sound of one hand clapping? And he will master his greatest fear. Night Boat is the story of his tremendous life.
