I am a Holy man, this Prince will grow into either a Great King, Military Man or Spiritual Leader.
Siddharha Gautama was born into luxury from the very beginning. A holy man went to see him and the King when he was young.
The King wanted his son to be a great King and forced him to stay in the royal palace so he didn't experience any hardship. Siddharha Gautama was married when he was 16 years old. He had a son. They all lived in luxury.
Gautama stayed in the palace until his late 20's. He was shocked when he left the castle he and saw a dead man, a very old person, a sick man and a holy man. Gautama wanted to know why this was happening. He wanted to search further.
Gautama was 29 and he decided to leave the palace for good. He left his wife and son and the luxury. He lived in the forest and nearly starved. He realised that this was the opposite extreme to luxury and instead decided to follow a middle path = Middle Way.
The next day he sat down and stared to meditate under a Bodhi tree. By meditation he managed to clear his mind and his thoughts. Gautama then realised that the ultimate goal to life is to reach Enlightenment, - to banish suffering - and to teach Enlightenment.
For the first time in Gautama's life he was complete. He had found peace and calm, he understood the reasons for suffering and how to overcome them by following the eight fold path to Nirvana. He became the Buddha, the founder of Buddhism.
