Review of the book Wisdom of Sadhu

I found out alot about this person by reading about his life.

He founded the religion Sikhism,about 1500 AD, is a religion that teaches belief in one God and rejects the caste system

The death of Sundar Singh's mother, when he was fourteen, pitched him into violence and despair. He took out his anger on the missionaries, persecuted Christian converts, and ridiculed their faith. In final defiance of their religion, he bought a Bible and burned it page by page in his home while his friends watched.

Sundar felt that his religious pursuits in Sikhism and the questioning of Christian and Hindu priests left him without ultimate meaning. Sundar resolved to kill himself by throwing himself upon a railroad track. He made a quest that whosoever is the 'True God' will appear before him Or else he would kill himself, that very night he had a vision of Jesus who opened Sundar's soul to the truth. Sundar announced to his father, Sher Singh, that henceforth he would follow Christ. His father denounced him, and his brother Rajender Singh attempted to poison him. Sundar's life was saved by the help of a nearby Christian community

On his sixteenth birthday, he was publicly baptised as a Christian in the parish church in Simla, in the Himalayan foothills. Prior to this he had been staying at the Christian Leprosy Home at Sabathu, near Simla, serving the leprosy patients there.

In October 1906, he set out on his journey as a new Christian, wearing a turban and the yellow robe of a Hindu sadhu, an ascetic devoted to spiritual practice. Singh viewed himself as a sadhu, albeit one within Christianity rather than Hinduism, because he realised Christianity could not penetrate India unless it was in an Indian way.

"I am not worthy to follow in the steps of my Lord," he said, "but, like Him, I want no home, no possessions. Like Him I will belong to the road, sharing the suffering of my people, eating with those who will give me shelter, and telling all men of the love of God."

After returning to his home village, where he was given an unexpectedly warm welcome, Sundar Singh travelled northward through the Punjab, over the Bannihal Pass into Kashmir, and then back through Muslim Afghanistan and into the brigand-infested North-West Frontier and Baluchistan. He was referred to as "the apostle with the bleeding feet" by the Christian communities of the north. He suffered arrest and stoning for his beliefs, and experienced mystical encounters.
