At the age of 29 Sidd rode out of the castle with no guards. During the ride he saw the Four Passing Sights. Sidd saw a dead man, a diseased, a man leaning on a stick, but the last he saw a holy homeless man. That night he cut his hair and traded his clothes for a simple robe.
Sidd began his search for the truth about life. He first studied with gurus, then later became a band of ascetics. He was so content to it, he barley ate. So one day he fainted, when he awoke he ate a bowl full of rice and a glass of milk, so the ascetics abandoned him.
Siddhartha became buddha by meditating for 49 days and not giving up, even when the god Mara tried temt him, he stood his ground and eventually he came to enlightenment
The buddha chose to go back to the world instead of enjoying his own liberation to teach others what he had learned. For the next 45 years he travled across India, preaching a message of truth and hope.
