Soon Siddhartha became disillusioned with the palace life and wanted to see the outside world. He made four trips outside the palace and saw four things that changed his life. On the first three trips, he saw sickness, old age and death. He asked himself, "How can I enjoy a life of pleasure when there is so much suffering in the world?"
On his fourth trip, he saw a wandering monk who had given up everything he owned to seek an end to suffering. "I shall be like him." Siddhartha thought.
