SIddartha left the kingdom because he craved spiritual satisfaction. On his first adventure he say an old man with a decrepit body. On his second adventure, Siddartha saw a sick man on the road. On his third adventure, he saw a dead body being cremated. Finally, on his last adventure, Siddartha saw a monk who was in severe denial. He was wearing a yellow robe and holding a bowl. Channa told Sidarthra that this man was looking for the answer on the riddle of life.
