Siddhartha Gautama will either become a very powerful ruler like his father or he becomes a holy man and your family will lose all power in the kingdom
His parents were told that if he was to be him away from sickness, aging, poverty, and death, he will become powerful so his parents secluded him in the house for his entire life.
Siddhartha grows up, gets married and has kids. One day, he takes his cart outside the palace where he sees an old man, a sick man, and a beggar monk in the street. He also drives by a dead man. He is stunned at this, the fact that people can live such terrible lives.
Siddhartha leaves his family and goes out to ask wise men to live life well. After not getting an answer, he decides to try becoming a starving monk. However, he became so thin that he came to the realization that starving himself will not make him any happier.
Instead, Siddhartha decides to meditate under a Bodhi tree until he finds a solution. A demon by the name of Mara tries to tempt him by offering many things but he resists and meditates for 49 days.
Siddhartha comes to the conclusion that humans are never satisfied and the suffering never ends. He becomes enlightened and goes by Buddha.
Buddha preaches and enlightens others . His friends become his disciples. He preaches in the idea of nirvana and it meaning being blown out of your desires and being free .
After Buddha dies, his disciples carry on his teaching and beliefs to spread to others across the world.
