This is how Buddhism was made, there was a prince and he was in a place and if he went out of it he would not be able to rule the kingdom, the palace had great food and great entertainment so he would not go away from the house but the prince knew that there was more to live so he went out of his palace, he encountered an old man, an sick man and a corpse during his travels, he found out that their desires made them like that then he became an ascetic then he meditated for a long time and he did not eat much, after he meditated under a tree for a month something happened it was nirvana, he started understanding the meaning of live then he thought it to other people then he became the Buddha ( Buddha means teacher in some language, I am not sure. )
