He will be a king, great like yourself, or a memorable spiritual teacher.
I must clear the way for my King's son!
Siddhartha Gautama was born into royalty in Nepal in the year of 563 B.C. Siddhartha's father, the King, met with a fortune teller to decide his son's future. The two ways that Siddhatha could go were: One, being mighty king, or a spiritual teacher. But of course the King wanted his son to take over as King one day.
Why was he happy? He had NOTHING.
Ascetics: No Pleasure.
Siddhath was raised in luxury and never felt pain. His guards always went ahead of him to clear the way of any poor, sad, or sick people. A parasol was always hovered above him for cleanliness.
It is said that when Siddhartha was the age of 29, he rode out without his guards. What he saw shocked him. The "four sights" were: One, an old man with a cane, two, a man with a disease, three, a dead man with a crying group around him, and four, a holy looking man who had nothing, but was content.
Siddhartha was inspired after seeing the "holy man" and he wanted to know how he was so happy with nothing. The prince started to beg for food, and would only eat what was placed into the begging bowl. Siddhartha studied gurus, a special spiritual teacher, who taught him about ascetics.
Siddhartha then joined a group of ascetics and was on the road to self denial; where you denied yourself of all pleasure. You have up your possessions and barely ate. Because of lack of food, Siddhartha's body was very weak, causing him to pass out. A milkmaid gave him food, and he realized self denial was not the was to learn the truth.
Because of Siddhartha eating the milkmaid's food, the ascetics left him behind. He was okay with all this because he knew it was not the way to the truth. He said he would sit under a bodhi tree until he uncovered the truth, which he finally did. He saw his past lives when he got into a deep state of meditation. He did not become in the state "nirvana" because he wanted to teach about what he learned so others could be taught about rebirth.
